Abstract:

Experiments were conducted to study the dispersed phase of coconut milk emulsion. They were optical microscopy analysis using a Nikon Microscope and particle size analysis using a Coulter Counter Multisizer. Particle size analysis using a Coulter Counter Multisizer on both original coconut milk and homogenized coconut milk at T = 19 °C indicated that they had a wide range of particle size with average value of 5.988 + 1 .0 pm and 6.696 + 1 . 1 pm in diameter respectively. Optical microscopy analysis showed that homogenization of coconut milk after it was heated in a water bath at T = 35 °C for about 15 minutes resulted in changes of particle size, the particle size became smaller. The result lead to a conclusion that the coconut milk emulsion may be considered as a polydisperse emulsion and it indicates that the system should not be sensitive to small variations in preparation or subsequent handling.

Abstract:

The structure formation influence on various macroscopic properties of fluid–fluid disperse systems is poorly investigated. The present work deals with the experimental study of the charge transfer in emulsions whose dispersed phase droplets are arranged into chainlike structures under the action of an external force field. The emulsions studied are the fluid system in which water droplets are dispersed in a hydrocarbon-based magnetic fluid. Under the effect of an external uniform magnetic field, anisotropic aggregates form from the emulsion dispersed phase drops. The low-frequency electrical conductivity of emulsions has been measured. It is demonstrated that the emulsions’ conductivity grows several times under the effect of magnetic field parallel to the measuring electrical field. The anisotropic character of the emulsion electrical conductivity in the presence of magnetic field has been demonstrated. It is revealed that the maximal response of conductivity on the magnetic field action takes place at the dispersed phase volume fraction of about 20%. The dynamics of the conductivity variation is analyzed in dependence on the magnetic field strength and the dispersed phase volume fraction. The obtained results may be of interest in the development of potential applications of disperse systems with magnetic-field-controllable properties.

Abstract:

New data on critical holdups of dispersed phase were measured at which the phase inversion took place. The systems studied differed in the ratio of phase viscosities and interfacial tension. A weak dependence was found of critical holdups on the impeller revolutions and on the material contactor; on the contrary, a considerable effect of viscosity was found out as far as the viscosity of continuous phase exceeded that of dispersed phase.

Abstract:

In order to optimize the composition and microstructure of quasicrystalline strengthened Mg-based alloy, the equilibrium phases of Mg-Zn-Y-Zr alloys with three components were studied by using thermodynamic calculation. The calculated results showed that the equilibrium phases of the three alloys were mainly Liquid phase, α-Mg matrix phase, α-Zr dispersed phase, quasicrystalline strengthening I phase, W phase and Z phase. It was observed that the specific content and temperature range of these phases were different. Among them, alloy 3 had the highest quasicrystalline content. And alloys 1 and 2 contained dispersed phase α-Zr which can lead to grain refinement.

Abstract:

This review analyzes two approaches to describing the polarization of disperse systems when an alternating electric field is applied in the general case. Polarization models of Trukhan and Dukhin – Shilov are considered. As a result of this review, it follows that the most preferable model, which makes it possible to significantly increase the rate of electrophoresis of the dispersed phase, is the Dukhin – Shilov model, in the implementation of which a giant dispersion of the dielectric constant of a heterogeneous dispersed system may appear if the condition of a thin double layer around non-conducting dispersed particles in a conducting dispersive medium.

Abstract:

The hydrodynamic characteristics of the liquid-liquid system of toluene-water in a pilot plant spray extraction column were experimentally determined. The experimental data for hydrodynamic characteristics such as the dispersed phase holdup, mean droplet size, and the axial dispersion coefficient were obtained. The dispersed phase superficial velocity had a great influence on toluene holdup. At the same time, a strong effect of the continuous phase superficial velocity on the dispersed phase holdup was evident. The dispersed phase holdup had a tendency to increase when the ratio of the dispersed phase superficial velocity and characteristic velocity increased. The Sauter mean droplet diameter decreased with increasing dispersed phase superficial velocity when the continuous phase superficial velocity remained constant. In contrast, it was not affected by the changes in the continuous phase superficial velocity while the dispersed phase superficial velocity remained constant. It was concluded that the Peclet number increased as a result of an increase of the Reynolds number.

Abstract:

Systematic experimental study has been performed to examine the effects of dispersed phase viscosity on emulsification in turbulence flow. It is found that the volume drop size distributions widen as dispersed phase viscosity increased; at lower dispersed phase viscosity, both Sauter mean diameter and the maximum stable diameter increase with the viscosity, while at higher dispersed phase viscosity, Sauter mean diameter and the maximum stable diameter decreasing and increasing, respectively. It has also been found that linear relation between the Sauter mean diameter and the maximum stable drop diameter is still valid for the emulsions which show a bimodal volume distribution, and the proportional constant decreases as dispersed phase viscosity increases.

Full text

Abstract:

The high temperature structural stability of nanograined NiCr alloys reinforced with nanoscale yttria and alumina dispersoids, fabricated by electron beam physical vapor deposition (EBPVD), was examined. The yttria particles coarsened very little and also inhibited grain growth in the matrix successfully, whereas the alumina dispersoids coarsened rapidly and were not as effective in restricting matrix grain growth. A hierarchy of phase transformations took place in the Al2O3 particles present as nano dispersoids in a nanograined NiCr matrix , on annealing. Coarsening of the alumina particles was accompanied by these phase transitions. The phase evolution is attributed to differences in free energies between the metastable and stable phases and a kinetic hierarchy in nucleation, brought about by structural and hence interfacial energy considerations.

Abstract:

Polypropylene (PP)/polyolefin elastomer (POE; ethylene–octene copolymer) blends with varying weight percentages of POE were prepared in a twin-screw extruder and molded through high shear rate injection-molding process. The morphologies and rheology of the PP/POE blends were systematically investigated based on rheological data and experimental analysis. The results indicate that the polymer blends of plastic and rubber in a high shear stress field result in a multilayered microstructure, which can be divided into skin, transitional, shear, and core layers according to the morphology of the dispersed phase. The morphology formation of the dispersed phase depends on the shear field and temperature field in the processing. Morphological evolution of the dispersed POE phases in PP matrix was described and quantified. A dragging ellipsoid model and capillary number were employed to describe the morphological evolution of the dispersed phase, and the morphological parameters were obtained. The results show that the dragging ellipsoid model is well suited to explain the morphological evolution of the dispersed phase in polymer blends molded under high shear rate.

Abstract:

The results of an earlier investigation that demonstrated the significance of the particle diameter/fluid length scale ratio in determining whether or not the addition of a dispersed phase would cause an increase or decrease in the carrier phase turbulent intensity are extended to radial locations other than the centerline. Presently, it is shown that similar trends are valid except the results become less correlated approacthing the wall for the case of pipe flows. The results for jets are independent of radial location. It is also shown that other possible non-dimensional parameters do not correlate the data as well.

Abstract:

Current trends in liquid-fueled practical combustion systems are leaving less tolerance for fuel injection deficiencies such as poor spray field symmetry. The present paper evaluates the symmetry of the flowfield produced by a practical airblast atomizer. Specifically, the influence of both the continuous phase and dispersed phase on the spray field symmetry is assessed. In the present case, asymmetry in volume flux is associated principally with disparities in the injection of the dispersed phase, which is manifested by a maldistribution of larger drops. Asymmetries observed in the continuous phase without the dispersed phase are reduced in magnitude by the presence of the dispersed phase, but still contribute to asymmetry in radial spread of the dispersed phase.

Abstract:

Compared with traditional insulation materials, such as cross-linked polyethylene (XLPE), polypropylene (PP) is famous for its better recyclable and thermal properties, as well as its good electrical performance. However, the problem of poor impact strength has restricted the application of pure PP in high-voltage, direct current (HVDC) cables. In this paper, styrene-ethylene-butylene-styrene block copolymer (SEBS) was used as a toughening filler, and nano-SiO2 was expected to improve the electric properties of the nano-composite. By controlling the masterbatch system, the dispersion characteristics of nano-SiO2 in the ternary composite system were changed. When PP/SiO2 was used as the masterbatch and then blended with SEBS, nano-SiO2 tended to disperse in the PP phase, and the number of nano-particles in the SEBS phase was lower. When PP/SEBS was used as the masterbatch, nano-SiO2 was distributed in both the PP phase and the SEBS phase. When SEBS/SiO2 was used as the masterbatch, nano-SiO2 tended to be dispersed in the SEBS phase. The different dispersion characteristics of nano-SiO2 changed the crystallization and mechanical properties of the ternary composite system and produced different electrical performance improvement effects. The results of our experiment revealed that the space charge suppression capability was positively correlated with the direct current (DC) breakdown strength improvement effect. Compared with the DC performance of 500 kV commercial XLPE materials, the self-made PP-based ternary composite system has better space charge suppression effects and higher DC breakdown strength. When nano-SiO2 was more dispersed in the PP phase, the space charge improvement effect was best. When the nano-SiO2 particles were more dispersed in the SEBS phase, the expected electrical property improvement was not obtained. Scanning electron microscopy showed that the nano-SiO2 particles in the SEBS phase were more dispersed at the interface than in the SEBS matrix, indicating that the nano-particles were poorly dispersed, which may be a reason why the electrical properties of the composite system were not significantly improved.

Abstract:

Materials performance plays a pivotal role to the smooth operation of present and future nuclear energy systems operating in severe irradiation environment in reactors. Therefore selection of structural materials with the desired properties is vital for this field of applications. The present work reports the effect of milling time during mechanical alloying of a novel Oxide Dispersed metal matrix composite consisting of multi-component AlCrFeMnNi high entropy alloy system with minor addition of Partially Stabilized Zirconia (PSZ) (1 wt.%). The main focus of this work is to understand the phase stability behaviour during mechanical alloying. High Entropy Alloy AlCrFeMnNi with Partially Stabilized Zirconia (PSZ) as Dispersoid phase was prepared by mechanical alloying. For study of phases, milled powder was investigated through X-Ray diffraction technique followed by Scanning Electron Microscopy for microstructural morphology. The study reveals that PSZ Dispersed AlCrFeMnNi alloy mainly consists of BCC (Fe Type) and FCC (Ni Type) mixed structure. At the end of 30 h lattice strain and crystallite size were measured to be 0.738 % and 13 nm respectively.

Abstract:

This work provides a review of hydrodynamic characteristics and mass transfer in the K?hni extraction columns. The experiments, as reported in the literature, were performed in the presence and absence of mass transfer. The results showed that the Sauter mean drop diameter was strongly affected by the rotor speed and interfacial tension, whereas the effects of the dispersed and continuous velocities were negligible. Empirical correlations for the Sauter mean drop diameter, taken from the literature, were discussed. It was experimentally determined that the dispersed-phase holdup depended to a great extent on the rotor speed, mass transfer direction between the phases, physical characteristics of fluids in the liquid-liquid system, and the dispersed-phase flowrate whereas it increased with the increase in mixing in the two-phase system and the ratio of phase flowrates. On the other hand, it has been shown that the mass transfer rate increases with increasing the level of back mixing. It was found that the mass transfer coefficient depends on the rotor speed and the direction of mass transfer between the phases. At the same time, it has been shown that the mass transfer coefficient depends relatively little on the phase flowrates. An empirical correlation was proposed for prediction of the overall mass transfer coefficient based on dimensionless numbers. Also, novel empirical correlations for prediction of the Sherwood number in the continuous phase were presented based on the dispersed-phase holdup, Reynolds number, and mass transfer direction between the phases. Empirical correlations based on dimensionless numbers can be considered as a useful tool for the design of the K?hni columns.

Abstract:

For simultaneous measurement of size and velocity distributions of continuous and dispersed phases in a two-phase flow a technique phase-Doppler anemometry was used. Spherical glass particles with a particle diameter range from 102 up to 212 ?m were used. In this two-phase flow an experimental results are presented which indicate a significant influence of the solid particles on the flow characteristics. The height of influence of these effects depends on the local position in the jet. Near the nozzle exit high gas velocity gradients exist and therefore high turbulence production in the shear layer of the jet is observed. Here the turbulence intensity in the two-phase jet is decreased compared to the single-phase jet. In the developed zone the velocity gradient in the shear layer is lower and the turbulence intensity reduction is higher. .

Abstract:

Composite material has many excellent properties, current, receives special attention was paid to its mechanical properties. By adding the dispersed phase can make the strength of the composites than did not join the dispersed phase of pure matrix material strength several times or several times. Composite materials are often called fiber ( or other dispersed phase) reinforced composite materials.

Abstract:

The influence of diameter, bending angle and bending radius of gas pipelines bends on the location and extent of their erosion wear is investigated. The research is carried out with the help of CFD (Computational Fluid Dynamics) simulation using the Lagrangian approach (Discrete Phase Model) in the ANSYS Fluent R19.2 Academic software. The mathematical model of the continuous-phase motion is based on the solution of simultaneous Navier-Stokes equations, the continuity of closed two-parameter k-ε model turbulence with the corresponding initial and boundary conditions. The motion trajectories of the dispersed phases are monitored by integrating the equations of forces acting on the particles. The simulation of erosion wear of the gas pipeline bends is performed using Finney equation. The investigations are carried out for five different external diameters of the pipeline bends (89 mm, 219 mm, 530 mm, 1020 mm and 1420 mm). The angles of the bends are 30°, 45°, 60°, and 90°, and the bend radii are DN, 1.5 DN, 2 DN, 2.5 DN, and 3.5 DN. Natural gas was selected as the continuous phase, and sand was selected as the dispersed phase. The flow rate of the disperse phase, the motion velocity of the dispersed and continuous phases at the inlet of the bend and the pressure at the outlet of every simulated bends are assumed to be the same. The simulation results are visualized in the ANSYS Fluent postprocessor by constructing erosion velocity rate fields on the contours of gas pipeline bends. On the basis of the visualized results, it is determined that the largest influence on the location of the erosion wear of the pipeline bends is caused by the bend radius, and the largest effect on the amount of the erosion wear is caused by bend diameter. The influence of the geometric parameters of the bends on the location of their maximum erosion wear field is established. Graphical dependences of maximum velocity of erosion wear of gas pipeline bends on their geometric parameters are constructed.
