Streszczenie:
The industry is becoming more interested in peripheral pumps because they are inexpensive, have low specific speeds, and are small. One of the more serious problems that may occur with any pump is cavitation. That has a significant impact on pump components, particularly the impeller. This work presents a detailed experimental study on prolonging impeller lifespan under cavitation conditions by studying the effect of impeller surface finishing and coatings on its lifetime. For this purpose, seven impellers, in addition to the original one of the peripheral pump, had prepared and treated. Three impellers with three different levels of arithmetic surface roughness (Ra) were produced using a low-cost and customizable hand grinding procedure. And four impellers have been coated thermally with four different erosion-resistant composite materials. All of the impellers were cavitated for 300 minutes at normal and one at high water temperatures. The result showed that the mass loss percentages with the smallest (Ra) of 0.35µm, and coated with yellow epoxy were 84.86% and 48.50% lower than the original impeller, respectively. Thus, improving the quality of impeller surface finishing, and thermal coatings are excellent method for increasing the impeller's cavitation erosion resistance and thereby extending its lifetime.

X-ray residual stress analysis was performed on four space shuttle hydrogen pump impellers made from Ti-5Al-2,5Sn alloy. Five locations on the outer rim, near the vanes, were measured on each impeller, identified as #1, #2,#3, and #4. Impellers #1 and #4 were test-fired impellers, impeller #2 was a new impeller that had been spin tested, and impeller #3 was a new impeller that had not teen spin tested. The measurement locations on these impellers corresponded to areas of critical stress importance. The purpose of the measurements was to compare the stresses at these locations as a function of impeller processing variables. A description of the Impellers, the test parameters and procedures, stress analysis results, and a technical discussion of these results are presented in this report.A description of the Impellers, the test parameters and procedures, stress analysis results, and a technical discussion of these results are presented in this report.

Abstract This paper extends knowledge about flow in an agitated batch with pitched blade multi-stage impellers. Effects of various geometrical parameters (blade number, distance between impellers) of pitched blade multi-stage impellers on pumping ability have been investigated. Axial velocity profiles were measured by LDA (Laser Doppler Anemometry). Axial pumping capacities were obtained by integration of measured axial velocity profiles in outflow from impellers. Main attention was focused on the effect of the distance between impellers in multi-stage configurations, on their pumping capacity and flow in the mixing bath in comparison with an independently operating pitched blade impeller with the same geometry. In case of a relatively close distance between impellers H3/d = 0.5 - 0.75, the multi-stage impeller creates only one circulation loop and the impellers itself behave identically as pumps in series. However for relative higher distance of impellers than H3/d = 1.25, the multi-stage impeller creates two separated circulation loops.

The work presents the computational study of the flow field in multiple impellers stirred vessel with various impeller types and configurations at 300rpm, 450rpm and 600rpm. Three types of impellers are investigated, namely the pitched blade impeller (PB), flat blade impeller (FB) and sawtooth impeller (ST). In this study, the flow patterns, turbulent kinetic energy dissipation, and power consumption in dual impellers system have been studied using computational fluid dynamics (CFD) by employing the multiple reference frame (MRF) and realizable k-ɛ turbulence model. The results from PBFB and reversed FBPB indicate efficient and powerful mixing with the merging of flows from both impellers that circulates the entire vessel. Besides, the FB and ST configuration exhibits the mixing characteristics that enhance both dispersion and mixing homogeneity. It is proven in this study that the combination of axial and radial impellers improves the weak mixing zones in the stirred vessel by the complex flow patterns produced. On top of that, utilizing two different impellers could achieve two mixing objectives in a system with the exceptional features of each impeller. The results establish promising effects of the reverse rotation in axial impellers and the arrangement of two different impellers in a multiple impeller system. With the rapid growth of industrialization, understanding the fluid dynamics in a multiple impeller stirred vessel is fundamental to optimize and scale up industrial mixing operations. Hence, the empirical findings in this study will be beneficial in selecting the suitable combination of impellers and the orientations that will enhance industrial mixing operations. Apart from that, the present work also illustrates that the computational technique used can be extremely valuable in determining the fluid dynamics in complex multiple impeller system which is challenging to analyse experimentally.

The paper deals with the influence of the number of impellers and the mode of aeration on the mechanical power input in a stirred gas-liquid dispersion using two impellers on the same shaft. Gas has been supplied either under the lower impeller or under both impellers. The power input was measured in the water-air system. A six-blade turbine impeller of the Rushton type and/or impellers with six inclined blades (with downward or upward pumping effect) were used. Experimental results have been obtained for a single impeller in a tank where the depth of liquid was equal to the tank diameter, and for different combinations of two impellers located on a single shaft where the distance between the impellers was equal to the tank diameter and the liquid depth was twice this diameter. It has been found that the power input data for the two-impeller system of two turbines can be correlated adequately by a simple equation. An estimate was made of the amount of gas supplied below the lower impeller which was transported into the region of the upper impeller.

The 3D flow field generated by two-stage impellers in the agitation of xanthan gum, a pseudoplastic fluid with yield stress, was simulated using the commerical CFD package. The effect of impeller speed and impeller spacing on power number, cavern size and viscosity distribution was investigated in this work. The results showed that the power number was slightly influenced by impeller spacing. Higher impeller speed and larger impeller spacing contributed to creation of a bigger cavern. The range of high viscosity zone between the impellers increased with an increase in impeller spacing. Impeller speed and impeller spacing could be used as important parameters to improve the mixing performance of multi-stage impellers in the mixing of pseudoplastic fluids with yield stress.

Reasonable methods for determining the optimum number of blades in a low specific speed centrifugal pump with closed-type impeller with splitters, i.e. compound impeller have been rather rare in the literature so far. In the article, a new analytical method was put forward to determine such an optimum number of blades by including the effect of turbulent boundary layer over impeller blades. Three conventional impellers with different numbers of full-length blades and two compound impellers with different numbers of splitters were designed and manufactured. The corresponding performance tests were then conducted. Results showed that the optimum numbers of blades exist for two kinds of impeller in terms of head at design point, pump efficiencies at design point and best efficiency point, and slope of head-flow rate curve at shut-off point. The estimated optimum numbers of blades are in good agreement with the numbers based on the experiments. The conventional impellers with full-length blades are more prone to the hump phenomenon than the compound impellers at the optimum numbers of blades. For the compound impellers, however, the hump effect is negligible at the optimum number of blades, and their head and efficiency are higher than those for the impellers with full-length blades. The method is applicable to compound impeller design in low specific speed centrifugal pumps.

The design of casting impeller’s processing technology is based on reducing metal removal of the impeller dynamic balance. Casting impeller is an efficient method for the production of impellers, the dynamic balance of precision casting impeller itself can be used to achieve the use requirement of the impeller. It can meet the requirement of dynamic balance as the impeller rotation when the axis of impeller’s symmetry axis as locating datum in the process of machining. It means reduced the metal removal of dynamic balance. We Put the impeller axis symmetry as the processing benchmark, and then design a processing method of shaft and impeller.

The outlet angle and shape of impeller blades are important parameters in centrifugal pump design. There is a lack of detailed studies related to double curvature impellers in centrifugal pumps in the current literature; therefore, an experimental and numerical analysis of double curvature impellers was performed. Six impellers were made and then assessed in a centrifugal pump test bed and simulated via 3D CFD simulation. The original impeller was also tested and simulated. One of the manufactured impellers had the same design as the original, and the other five impellers had a double curvature. Laboratory tests and simulations were conducted with three rotation speeds: 1400, 1700, and 1900 RPM. Head and performance curve equations were obtained for the pump–engine unit based on the flow of each impeller for the three rotation speeds. The results showed that a double curvature impeller improved pump head by approximately 1 m for the range of the study and performance by about 2% when compared to basic impeller. On the other hand, it was observed that turbulence models such as k-ε and SST k-ω reproduced similar physical and numerical results.

This paper investigated the variable speed operation of a two-way contra-rotating axial flow pump–turbine in pump mode. When counter-rotating impellers operate at the same speed, a significant difference exists in the shaft power of the two impellers, thereby causing difficulties in motor selection. However, the same motor is required for both impellers in two-way pump–turbines. To solve this problem, this paper aims to determine the appropriate speed at which the two impellers operate with a similar shaft power. Accordingly, improving the performance of the tidal unit while enabling the basic functions of the pump–turbine is of considerable engineering and academic significance. An analysis of performance variations of the front and rear impellers in the pump mode reveals the law of power variation for each impeller at different speeds of the rear impeller. Under different flow conditions, shaft power of the rear impeller is found to be at least 31% higher compared with that of the front impeller. This result provides practical reference for further research on the operation of counter-rotating axial flow pump–turbine.

An experimental and theoretical study of erosion in centrifugal compressor impellers is presented. An experimental rig using laser anemometry techniques was employed to create a database of particle restitution ratios for a range of materials. This data was unique in that the particle rebound was measured in a quiescent condition where the aerodynamic effects had been minimised, and also parametric factors not previously available were included. These values were incorporated into the existing Particle Trajectory Code developed by Cranfield University and Rolls Royce PLC. The code is used to calculate the trajectories of discrete particles in three dimensional gas turbine geometries, and the ensuing erosion. It was modified to include the effects of the periodic boundary conditions, particle fragmentation, splitter blades, and variations in inlet dust concentration profile. Flowfield calculations were performed on a Rolls Royce GEM-2 and splittered GEM-60 impeller, which both represent the high pressure stage of the axial + centrifugal compression system of GEM engines. A procedure developed by Tourlidakis, for the analysis of steady viscous flow in high speed centrifugal compressors with tip leakage, was used to generate the flowfields. The GEM-2 impeller flowfield was analysed at 1009c speed, and validated with calculations and measurements which had been taken for previous projects. Simulated erosion data under the same conditions was checked using practical results obtained in a Rolls Royce PLC Helicopter Engine Environmental Protection Programme, and good agreement was achieved. In order to provide a qualitative, experimental assessment of erosion, a GEM-60 impeller was coated with four layers of paint of different colours. Two sizes of quartz particle, each at three different vane heights, were then seeded into the impeller while it was run cold at (the maximum) 70% speed. The erosion patterns generated compared well with the results generated by the Particle Trajectory Code.

Streszczenie:
This thesis presents models and algorithms necessary to simulate the five-axis flank milling of jet-engine impellers in a virtual environment. The impellers are used in the compression stage of the engine and are costly, difficult to machine, and time-consuming to manufacture. To improve the productivity of the flank milling operations, a procedure to predict and optimize the cutting process is proposed. The contributions of the thesis include a novel cutter-workpiece engagement calculation algorithm, a five-axis flank milling cutting mechanics model, two methods of optimizing feed rates for impeller machining tool paths and a new five-axis chatter stability algorithm. A semi-discrete, solid-modeling-based method of obtaining cutter-workpiece engagement (CWE) maps for five-axis flank milling with tapered ball-end mills is developed. It is compared against a benchmark z-buffer CWE calculation method, and is found to generate more accurate maps. A cutting force prediction model for five-axis flank milling is developed. This model is able to incorporate five-axis motion, serrated, variable-pitch, tapered, helical ball-end mills and irregular cutter-workpiece engagement maps. Simulated cutting forces are compared against experimental data collected with a rotating dynamometer. Predicted X and Y forces and cutting torque are found to have a reasonable agreement with the measured values. Two offline methods of optimizing the linear and angular feeds for the five-axis flank milling of impellers are developed. Both offer a systematic means of finding the highest feed possible, while respecting multiple constraints on the process outputs. In the thesis, application of these algorithms is shown to reduce the machining time for an impeller roughing tool path. Finally, a chatter stability algorithm is introduced that can be used to predict the stability of five-axis flank milling operations with general cutter geometry and irregular cutter-workpiece engagement maps. Currently, the new algorithm gives chatter stability predictions suitable for high speed five-axis flank milling. However, for low-speed impeller machining, these predictions are not accurate, due to the process damping that occurs in the physical system. At the time, this effect is difficult to model and is beyond the scope of the thesis.

Streszczenie:
Computational Fluid Dynamics (CFD) techniques have settled to a stage, where it is possible to gain significant insight into fluid flow processes of turbomachinery. However, the purpose of fluid dynamics naturally goes beyond improved understanding to the aim of improving the performance of the engineering systems. Consequently, the present thesis investigates the use of a automated design optimisation method using CFD. This presents a new design method for a important turbomachinery part, blade profiles of centrifugal pump impellers, based on a shape optimisation algorithm in combination with CFD. The use of genetic algorithms in shape optimisation dose not allow the design engineer to use any derivative information on the evolution of the shape, but only simple evaluation techniques. A optimisation library (GAlib), based on a genetic algorithm (GA), was used. GA controls the evolution of a population of profiles towards an optimum design. The optimisation process can handle simple objectives as well as conicting ones. The fitness value of each population element is evaluated using a CFD flow solver (Mac_LNS) based on nite-difference discretisation of the incompressible, Navier-Stokes (N-S) equations on structured polar-coordinate meshes. A number of design examples have been developed and the behaviour of the genetic algorithm has been tested using different kinds of objective functions. I addition, the algorithm was tested with a multi-objective mction. Bézier curves were selected to represent the impeller profile. A symmetric profile, identical profile for the pressure side (PS) and suction side (SS), was used as a basic shape to generate the population elements. GAlib was modified to run as a parallel algorithm using Message Passing Interface (MPI). It is indicated that parallelisation using MPI is good technique to overcome the time taken by GA and CFD, and quite good optimisation convergence criteria was obtained by using parallelisation. The obtained results show that the genetic algorithm is capable of achieving satisfactory designs of centrifugal impeller blade profiles effectively and with a minimum amount of user expertise.

AbstractAdditive Manufacturing (AM) is a key Fourth Industrial Revolution (4IR) technology in which parts are manufactured directly from 3-dimensional models through selective deposition of materials. As a digital technology, AM can be used to produce complex parts that are difficult to make using traditional methods without the need for tooling. Hence, the aim of this study is to investigate the performance of Fused Deposition Modelling (FDM) in the manufacture of pump impellers. This involves performing simulation to test the performance of pump impeller under real-life working conditions at different operating speeds and pressures. The model of the impeller as casted in the FDM process was developed in the complete Abaqus modelling environment. The model part was created as single solid homogenous part with no nodal separations or assembly ties or constraints between the base of the impeller and its blades, in relation to its as-cast manufacturing state. The results obtained showed that extreme operating speeds of up to 1000 rad/s or pressures of 0.22 MPa are not suitable conditions under which the impeller will operate without compromising its efficiency and structural integrity. The study is useful in providing guidance on the application of FDM to produce functional parts. Through the study, the capability of AM as a suitable approach for enabling local sustainable production of spare parts is demonstrated.

Streszczenie:
Low specific speed, namely low flow coefficient, Wedge type impellers with high performance are developed, which impellers are applied to high-pressure multistage compressors. Conventional low specific speed impellers because of their low volume flow rates have thin blades and their blade heights are small. Therefore, efficiency of low specific speed impellers turns out to be lower than that of high specific speed impellers, because the large wetted perimeter causes large skin friction loss. Wedge type impellers with thick blades and large blade heights are examined to reduce the skin friction loss. Blade geometry of Wedge type impellers is determined by the distribution of blade angles and thicknesses that are defined in terms of a polynomial of meridional distance. The determination of impeller geometry also takes into account the inlet and the outlet blade heights. Adiabatic efficiency of many Wedge type impellers, designed by studying various combinations of these distributions and blade heights, is estimated by the one-dimensional prediction method. This procedure leads to the determination of optimized impeller geometry with higher efficiency and wider operating flow range than available otherwise. In Wedge type impeller optimization by their design, the relative velocity ratios from impeller “inlet to throat” and from impeller “inlet to outlet”, and flow incidence at impeller inlet are restricted to certain specific values. This is done in order to ascertain wide operating flow range. Estimated efficiency of optimized Wedge type impeller with designed suction flow coefficient of 0.021 is by some percent higher than that of the conventional two-dimensional impeller with thin blades, as was determined by both the one-dimensional prediction method and by commercial CFD code. Designed Wedge type impellers were fabricated and tested for their aerodynamic performance. Results show that in case of Wedge type impeller the normalized stage efficiency increases by 6% and operating flow range expands significantly as compared with those of the conventional 2D impeller stage. The performance estimation by CFD also shows a qualitative agreement with the experimental results regarding the increase in efficiency and operating flow range. Moreover, rotating stall which often exhibits sub-synchronous low frequency shaft vibration in high-pressure centrifugal compressors was not observed in Wedge type impeller stages.

Today, there are 3 primary methods Solar Turbines, Inc. uses for manufacturing shrouded centrifugal impellers for the Oil and Gas industry. Impellers can be made by an investment casting process, single piece integrally-machined using point milling, or fabricated using a flank milled, open faced impeller and brazing a shroud in place. Investment cast impellers give the aero designer the greatest flexibility in the design, since the designer doesn’t need to be concerned about tool access or other manufacturing constraints. It is common to use this process for any impeller. Single piece integrally-machined impellers are relatively straightforward for high flow coefficient impellers, as the wide flow-path provides plenty of room for tool access. For lower flow coefficients, brazed shrouded impellers can be made very precisely, but at a substantially higher cost than the other methods. Each of these manufacturing methods also has a cost and aerodynamic performance associated with them. With the advent of high-speed machining and better cutting tools, integrally-machined impellers can offer an alternative manufacturing process over cast or fabricated impellers. However, determining the ability to integrally-machine an impeller historically is done late or even after the detailed design process. This can lead to costly redesigns to make sure the impeller can be machined, with flow-path and blade adjustments done after the aerodynamic design. Sometimes these adjustments are unsuccessful and the manufacturing process is abandoned. In this paper, 2 medium flow coefficient impellers are redesigned. These impellers are used in pipeline applications for the transmission of natural gas. The original designs were cast. By incorporating highly customized commercial software written exclusively for defining tool paths of integrally-machined shrouded impellers into the aerodynamic design process, new impeller geometry was defined that was able to be integrally-machined, while meeting or exceeding existing impeller performance and improved design cycle time. This paper will discuss how the machining software was used concurrently with CFD and FEA analysis during the design process. Test results from rig tests will be presented, showing measured results from both the original and redesigned stages.

The present paper deals with two different subjects in the field of centrifugal compressors, namely impeller design and its aerodynamic analysis. The paper provides results of aerodynamic design of low specific speed centrifugal compressor impellers. The design objective is the improvement of the efficiency of a 2D-impeller by means of a 3D-impeller design. The design volume flow and isentropic pressure coefficient of the 3D-impeller should be similar to the one of the 2D-impeller. The numerical CFD (Computational Fluid Dynamics) analysis comprises non-dimensional results of overall impeller and stage performance as well as flow details (circumferentially averaged fluid properties in the impeller exit plane). Furthermore, the paper presents the analysis of secondary flow development of different impellers in comparison with a 2D-impeller of prismatic blade profile. The numerical analysis focuses on understanding of different development of the impeller secondary zone. Results show a direct correlation between the overall performance and secondary flow of the different impellers providing more insight into the aerodynamic philosophy of design of centrifugal compressor impellers.

The prediction of the dynamic behaviour of the impellers is of considerable importance in the design of turbomachines. The excitation possibilities of the radial impellers by the forces or imposed displacements are various and an appreciation of the life of radial impellers is strongly bounded to an accurate dynamic analysis. Therefore, it is necessary to analyze them in order to improve the geometry or modify the design. In order to better understand and explain the dynamic behaviour of impellers, a series of impeller models with various numbers of blades of radial or tangential extention have been examined. Because of complexity of analytical analysis shown in earlier works, the eigenfrequencies and modes of the impellers were evaluated using a Finite Element program. Interferometric holography served as a means to visualize the dynamic behaviour of the impellers. An experimental modal analysis was used to identify the modal parameters. A detailed application of these methods to an actual centrifugal impeller was also reported along with theoretical and experimental investigations on the impeller models.

This paper proposed a three-dimensional finite element stress analysis technique for radial flow impellers which has the following characteristics: utilizing the cyclic symmetry of geometry, load, and boundary condition of an impeller; and modelling an impeller in a realistic manner. The detailed stress analyses for four impellers have been carried out using the program TDSAI based on the technique. Here the analysis for one of them with curved blades is described. The finite element results for the impeller and another straight-radial-bladed impeller are compared with the photo-elastic results for the same impellers.

This paper presents a unified slip model for axial, radial, and mixed-flow impellers. The core assumption of the model is that the flow deviation or slip velocity at impeller exit is mainly originated from the blade loading near the discharge of an impeller and its subsequent relative eddy in the impeller passage. The blade loading is estimated and then used to derive the slip velocity using Stodola’s assumption. The final form of the slip factor model can be successfully related to Carter’s rule [1] for axial impellers and Stodola’s [2] slip model for radial impellers, making the case for this model to be applicable to axial, radial, and mixed-flow impellers. Unlike conventional slip factor models for radial impellers, the new slip model suggests that the flow coefficient at the impeller exit is an important variable for the slip factor when there is significant blade turning at the impeller discharge. This explains the interesting off-design trends for slip factor observed from experiments, such as the rise of the slip factor with flow coefficient in the Eckardt A impeller [3]. Extensive validation results for this new model are presented in this paper. Several cases are studied in detail to demonstrate how this new model can capture the slip factor variation at the off-design conditions. Furthermore, a large number of test data from more than 90 different compressors, pumps, and blowers were collected. Most cases are radial impellers, but a few axial impellers are also included. The test data and model predictions of the slip factor are compared at both design and off-design flow conditions. In total, over 1,650 different flow conditions are evaluated. The unified model shows a clear advantage over the traditional slip factor correlations, such as the Busemann-Wiesner model [4], when off-design conditions are considered.

The optimum shape of high specific speed impeller is usually axial flow impeller. The radial impeller is often used without axial flow guidevane. Usually, the radial impeller is the high pressure and low specific speed impeller. The design parameters of radial high specific speed impeller have not been obtained yet. In the previous papers, the optimum meridian shape of axial flow impeller with axial flow guidevane is obtained for various specific speed. The optimum meridian shapes calculated by diffusion factor agree with meridian shapes of conventional impellers. In this paper, the design parameters of radial high specific speed impellers without guidevane are calculated by diffusion factor. And the optimum meridian shapes of radial high specific speed impellers are proposed. In case of the radial impeller, the hub diameter is equal to the tip diameter in impeller outlet. So, in radial impellers, the outlet hub-tip ratio is 1.0. The optimum meridian shapes of radial impellers for various specific speed are also obtained in this paper. The relative efficiency and cavitation performance of impellers in various shape factors were calculated. The calculation of radial meridian shape needs four kinds of shape factors as the previous papers. The four shape factors are inlet relative flow angle β1, turning angle Δβ, axial velocity ratio (meridian velocity ratio) kc = Cm2/Cm1 and impeller diameter ratio kd = D1c/D2c inmid span streamsurface. In initial step of impeller design, the result of the efficiency and cavitation performance of impeller calculated in optimum principal design parameters is important. The principal design parameters are hub-tip ratio, inlet-outlet diameter ratio, axial velocity ratio, solidity, inlet flow angle, turning angle and blade number. The author proposed the optimum meridian profile design method by diffusion factor for various condition of design parameters. There is a good correlation between the optimum hub-tip ratio and the specific speed considering cavitation performance. The optimum solidity is obtained for the specific speed considering efficiency and cavitation performance. It was found that the optimum meridian profile of high specific speed impeller with appropriate efficiency and cavitation performance has large inclination on hub and tip stream lines. The calculated data base is four dimensional using four various shape parameter β1, Δβ, kc and kd. Using the four shape factor, the optimum meridian shape of radial flow impeller is able to be obtained. The best 1000 optimum design parameters are selected using four dimensional calculated data. The aspect of optimization is recognized with 1000 plotted data on 6 planes. The result of radial flow impeller optimization is different from that of axial flow impeller. In case of axial flow impellers, the shape factors are optimized for each specific speed. But, in radial flow impellers, if both the specific speed and the total head coefficient are given, the optimum shape factors are optimized. The calculation results between profiles and specifications were very useful for the development of new type high specific speed radial impellers.

Abstract The shrouded and unshrouded impellers are two typical kinds of impellers, which are widely utilized in centrifugal compressors of various applications. Centrifugal compressors with unshrouded impellers are generally recognized to display inferior performance to the shrouded impellers with the same geometry. In this paper, a comparative experiment shows some results inconsistent with conventional cognition. Measured performance indicates that the peak efficiency of the centrifugal compressor with an unshrouded impeller is higher than the shrouded one, where the two impellers have the same geometry of meridional profile and blade central plane, and matched the same vaneless diffuser and volute. In order to explore the causes of this divergence, the effects of factors such as blade thickness, surface roughness of components, tip clearance and sealing leakage characteristics on performance are analyzed by CFD code. Numerical results show that reasonable reduction in the blade thickness and improvement on the surface quality of the impeller could effectively increase the peak efficiency and the choke mass flow rate of the shrouded impeller. The unshrouded impeller with arbitrary blade surfaces would be deformed under the action of centrifugal force to achieve a small tip clearance during operation, and then obtains higher efficiency at design speed. The research results are helpful to evaluate the performance potential and sensitive design parameters of shrouded and unshrouded impellers.

A comparison is made between the flow in two impellers, one with radially ending blades and one with blades backswept by 30°. The two impellers have identical inducers. Measurements are made of the three velocity components and total pressures across five measurement stations within each impeller. The flow in the backswept impeller is dominated by a counter-clockwise vortex which reduces the severity of the shroud boundary layer separation and hence leads to a higher impeller efficiency. The wake is consequently smaller in the backswept impeller but adopts a similar position on the shroud surface at the impeller exit. Analysis of the secondary flow generation reveals the mechanisms responsible for the differences in the flow fields in the two impellers.

Centrifugal pump impellers for wastewater applications have to be designed to meet additional requirements compared to clearwater pumps. Therefore these impellers usually have only one to three relatively thick blades and large width to diameter ratios. The presented study deals with the effect of trailing edge modifications, especially under-filing, to this class of impellers. Two wastewater pump impellers with different specific speeds have been investigated numerically and a detailed loss analysis has been made for the impellers with default and modified trailing edge configurations. In case of the impeller with lower specific speed the head but not the efficiency could be increased by trailing edge under-filing. For the impeller with higher specific speed, under-filing resulted in an significant increase in head and efficiency. The analysis of the losses showed how the losses in different sections of the impeller are affected by the trailing edge modifications and how and under what circumstances the efficiency can be increased in this way. Experiments on the test rig confirmed the numerical results and stated an increase in head of 7.7 percent at no increase in efficiency for the impeller with the lower specific speed and an increase in head of 11.7 percent at an efficiency gain of 1.7 percent at the design flow-rate and even 4.4 percent increase in maximum efficiency for the impeller with higher specific speed.

The vertical can booster pump is used extensively in pipeline service where low suction pressures prevent the use of above-grade horizontal pumps. These typically appear at storage terminals for transferring oil from storage vessels (tanks) to large pipeline pumps or to other storage vessels. The pump is capable of moving oil with very low inlet pressures by virtue of placing the motor at the top and the impellers at the bottom of the pump often well below grade and using the static pressure generated by the oil through the vertical elevation difference to ensure that the suction requirements of the pump is met. The booster pumps are often improperly designed or selected and further are misapplied or inappropriately used. The industry standards for vertical can booster pumps, are generic and do not consider all of the special requirements and service needs in pipeline applications. The missing information must be considered if a long life is expected from the pumps. This study examines and reports on the best booster pump practices considering the unique design issues for pipelines and further how the pumps should be specified, operated and maintained to ensure long term service. This report has a related webinar.
