In the pulping industry, thermo-mechanical pulping (TMP) as a subdivision of the refiner-based mechanical pulping is one of the most energy-intensive processes where the core of the process is attributed to the refining process. In this study, to simulate the refining unit of the TMP process under different operational states, the idea of machine learning algorithms is employed. Complicated processes and prediction problems could be simulated and solved by utilizing artificial intelligence methods inspired by the pattern of brain learning. In this research, six evolutionary optimization algorithms are employed to be joined with the adaptive neuro-fuzzy inference system (ANFIS) to increase the refining simulation accuracy. The applied optimization algorithms are particle swarm optimization algorithm (PSO), differential evolution (DE), biogeography-based optimization algorithm (BBO), genetic algorithm (GA), ant colony (ACO), and teaching learning-based optimization algorithm (TLBO). The simulation predictor variables are site ambient temperature, refining dilution water, refining plate gap, and chip transfer screw speed, while the model outputs are refining motor load and generated steam. Findings confirm the superiority of the PSO algorithm concerning model performance comparing to the other evolutionary algorithms for optimizing ANFIS method parameters, which are utilized for simulating a refiner unit in the TMP process.

Global demand for dissolving pulp has been increasing at a remarkable pace over the last few years. A shortage in cotton and the expansion of the textile, hygiene, and health product markets are behind this booming demand. The Canadian pulp and paper industry has entered these markets by converting several paper-grade pulp mills to dissolving pulp producers. In the kraft process, part of the hemicellulose remains with the pulp after cooking and the rest is burnt in the recovery boiler to produce energy. In dissolving pulp mills, most of the hemicellulose must be removed from the wood chips in a pre-hydrolysis stage before pulping. Hemicellulose hydrolysis and its subsequent extraction will affect energy and chemical balances. In addition, the new operation will require large capital expenditures. The objective of this work was to study the conversion of a kraft pulp mill to a dissolving pulp operation and the extraction of hemicelluloses from the process. The effects of hemicellulose extraction on mill energy balance, equipment requirements, and new operating conditions were analyzed. Computer simulations of the process and thermal pinch analysis were used. The existing bottlenecks (digesters, lime kiln, and recovery boiler) to increasing the dissolving pulp production capacity were identified before and after the conversion. In addition, energy efficiency measures were identified to decrease the energy consumption of the new process.

The Purdue model was adapted to simulate an industrial Lo-Solids pulp digester using ad-hoc reac-tion kinetics for Pinus radiata cultivated in Chile. Simulation results for blow line kappa number, pulp yield, free liquor temperature profile, and pulp production rate all agreed well with pulp mill data from Celulosa Arauco y Constitucion’s Arauco plant in Chile. Researchers then applied the mathematical model to simulate an increase in fil-trate flow to the modified continuous cooking zone to save white liquor consumption, keeping blow kappa number at its target value. Simulation results show a 9.1% savings of white liquor and a significant decrease in dissolved sol-ids content, thus improving the Lo-Solids pulping process.

A refining model is developed to analyses the refining process’s energy efficiency based on the refining variables. A simulation model is obtained for longer-term refining energy analysis by further developing the MATLAB Thermo-Mechanical Pulping Simulink toolbox. This model is utilized to predict two essential variables for refining energy efficiency calculation: refining motor-load and generated steam. The conventional variable for presenting refining energy efficiency is refining specific energy consumption (RSEC), which is the ratio of the refining motor load to throughput and does not consider the share of recovered energy from the refining produced steam. In this study, a new variable, corrected refining specific energy consumption (CRSEC), is introduced and practiced for better representation of the refining energy efficiency. In the calculation process of the CRSEC, recovered energy from the refining generated steam is considered useful energy. The developed model results in 160% and 78.75% improvement in simulation model determination coefficient and error, respectively. Utilizing the developed model and hourly district heating demand for CRSEC calculation, results prove a 22% annual average difference between CRSEC and RSEC. Findings confirm that the wintertime refining energy efficiency is 27% higher due to higher recovered energy in the heat recovery unit compared to summertime.

Mechanical products are becoming increasingly precise after industrial revolutions. Design is important for the manufacture of those products. Good mechanical design can improve the quality of product, and the efficiency of manufacture. To find the problems in the design and then improve the design, it needed the simulation process after the mechanical design was completed. Computer technologies in simulation process, such as software technology and virtual technology, were deeply studied in this work which combined practice with the concept and characteristics of machine design.

The conventional design of forming rolls depends heavily on the individual skill of roll designers which is based on intuition and knowledge gained from previous work. Roll design is normally a trial an error procedure, however with the progress of computer technology, CAD/CAM systems for the cold roll-forming industry have been developed. Generally, however, these CAD systems can only provide a flower pattern based on the knowledge obtained from previously successful flower patterns. In the production of ERW (Electric Resistance Welded) tube and pipe, the need for a theoretical simulation of the roll-forming process, which can not only predict the occurrence of the edge buckling but also obtain the optimum forming condition, has been recognised. A new simulation system named "CADFORM" has been devised that can carry out the consistent forming simulation for this tube-making process. The CADFORM system applied an elastic-plastic stress-strain analysis and evaluate edge buckling by using a simplified model of the forming process. The results can also be visualised graphically. The calculated longitudinal strain is obtained by considering the deformation of lateral elements and takes into account the reduction in strains due to the fin-pass roll. These calculated strains correspond quite well with the experimental results. Using the calculated strains, the stresses in the strip can be estimated. The addition of the fin-pass roll reduction significantly reduces the longitudinal compressive stress and therefore effectively suppresses edge buckling. If the calculated longitudinal stress is controlled, by altering the forming flower pattern so it does not exceed the buckling stress within the material, then the occurrence of edge buckling can be avoided. CADFORM predicts the occurrence of edge buckling of the strip in tube-making and uses this information to suggest an appropriate flower pattern and forming conditions which will suppress the occurrence of the edge buckling.

New computer technologies are applied to the classical material engineering two-body abrasive wear process. The computer simulation provides an interactive and visual representation of the wear process. The influence of grit size, grit tip radius and load (at constant workpiece hardness and tool path) on the wear rate, wear coefficient and wear surface topography is predicted. The simulation implements microcutting and microploughing with material displacement to the sides of the groove. The validation of the simulation is demonstrated by comparing with the previous modelling literature and with experiments.

The primary concern associated with a two-stroke engine performance is its gas exchange process (scavenging process). The success of the scavenging process greatly affects the thermodynamic properties of cylinder content at the trapping conditions and hence the combustion and power output. The unsteady gas flow in engine pipes has a marked influence on the scavenging process. In the current study, the two-stroke engine simulation model has been developed to predict the steady state performance characteristics of a crankcase compressed, piston port-timed, two-stroke engine equipped with expansion chamber. The characteristics include parameters such as engine torque and power, BSFC, scavenging efficiency and charging efficiency. The model also has the ability to predict the unsteady gas dynamic behaviour in various engine pipes. The instantaneous pressure fluctuation and mass flow rates at inlet port, transfer port and exhaust port were calculated and analysed. The model has several advantages compared with other one-dimensional isentropic model. It includes an improved procedure to account for the variation in geometry of pipe and to determine the thermodynamic states in cylinder/crankcase. The model also considered the temperature discontinuity at port/pipe interface. All these efforts increase the accuracy and numerical stability of the prediction. A single cylinder two-stroke engine dynamometer rig and dedicated fast data acquisition hardware and software have been developed in the project. Engine torque, speed and fuel consumption can be measured on the dynamometer rig. The dynamic pressure signals in engine cylinder, transfer port and exhaust port, together with crankshaft position signal, can be acquired at a speed of 50,000 sample/second per channel, sufficient for accurate acquisition of experimental data. Substantial simulations and experiments were performed and the computer model was validated. A variable exhaust system, as described in this study, was used to improve a twostroke engine's performance under off-design engine speeds. This was realised by making the mid-parallel section of a conventional expansion chamber extendable, while the other dimensions of that chamber remained unchanged. In the study it was found that with the adjustable expansion chamber, the pressure wave timing at the exhaust port was under control within the test speed range (2200 - 4400 RPM) so that such wave timing matched the engine port timing, leading to a relative optimum in performance. The numerical approach proposed could satisfactorily handle the complicated pipe flow calculation and predict both engine performance and dynamic wave variations in the test engine. Thus the program can be used for improving the design and development of naturally aspired, port-controlled crankcase compressed two-stroke engines.

AbstractIn the frame of a statistical tolerance analysis of complex assemblies, for example an aircraft wing, the capability to predict accurately and fast specified, very small quantiles of the distribution of the assembly key characteristic becomes crucial. The problem is significantly magnified, when the tolerance synthesis problem is considered in which several tolerance analyses are performed and thus, a reliability analysis problem is nested inside an optimisation one in a fully probabilistic approach. The need to reduce the computational time and accurately estimate the specified probabilities is critical. Therefore, herein, a systematic study on several state of the art simulation methods is performed whilst they are critically evaluated with respect to their efficiency to deal with tolerance analysis problems. It is demonstrated that tolerance analysis problems are characterised by high dimensionality, high non-linearity of the state functions, disconnected failure domains, implicit state functions and small probability estimations. Therefore, the successful implementation of reliability methods becomes a formidable task. Herein, advanced simulation methods are combined with in-house developed assembly models based on the Homogeneous Transformation Matrix method as well as off-the-self Computer Aided Tolerance tools. The main outcome of the work is that by using an appropriate reliability method, computational time can be reduced whilst the probability of defected products can be accurately predicted. Furthermore, the connection of advanced mathematical toolboxes with off-the-self 3D tolerance tools into a process integration framework introduces benefits to successfully deal with the tolerance allocation problem in the future using dedicated and powerful computational tools.

Under thermally activated deformation condition extensive formability may be obtained. In this paper, elevated-temprature formability and tube forming process [1] were analyzed. Two most typical tube forming process, tube free expansion and in-die bulge forming, were simulated by FEA with the use of Abaqus/Standard code. An empirical material equation was used that takes into account bothe starain handening and strain rate heardening effects, to reflects, to reflect material characteristics at high strain rates and at elevated tempratures. For tube free expansion forming, the deformation path was varied by changing the end velocity with respect to internal gas pressure, thus providing an assessment of material forming limit at various strain path. Falure to may occur due to necking and bucking, which are related tko the ratio of internal pressure and end-load. The deformation process and limit strain were obtained for various meterial parameters, including n-value and m-value, as well as the tempreture distribution. The effect of tube gemetry (diameter, thickness and heating length) on the process is also investigated. For in-die tube forming process, the effect of die friction on the material flow and strain distribution was analyzed, and the thickness distributions in the longitudinal direction (for axi-symmetrical tube forming) and in the circumferential direction (for round-to-squared tube forming) were predicted as function of forming parameters. A comparison between prediction and experiment was provided.

Abstract Resin transfer molding is one of the most common fabrication methods for composite materials. It is attractive due to its high volume, high performance, and low cost manufacturing of polymer composites. In this process, a dry preform of reinforcing fibers is placed inside a closed mold; then the resin is injected into the mold cavity. The composite part can be removed from the mold after the resin cures. This paper surveys current issues in the resin transfer molding process and focuses on mold filling and simulation. The Control Volume Finite Element Method is applied to simulate the process. The 2-D and 3-D computational methods are presented. The simulation program was developed with C language by the authors. The 2-D and 3-D models were integrated in the program. In real applications, the 2-D elements and 3-D elements can be applied simultaneously according to the specific requirements. MSC/PATRAN 3 software (MacNeal-Schwendler Corporation) was used to generate the finite element mesh and display the results. Some case studies are conducted to demonstrate the application of the computer simulation to RTM process design.

The anisotropic nature of laminated composites creates a unique opportunity and also a great challenge for tailoring their behavior during the forming processes according to the design requirements. In this work, design and simulation of a deep drawing process for fiber-reinforced laminated composites were conducted by using finite element analysis. The effects of the fiber orientation and stacking order on the deep drawing process were investigated based on the basic understanding of forming process of the isotropic aluminum alloy (Al-1100) and laminated composite material (Grilon RVZ-15H nylon/glass). A three dimensional finite element model incorporating layered structural laminates with various fiber orientations was developed. The load-stroke relationship, changes in thickness, and stress-strain distribution were investigated and compared for both aluminum alloy and laminated composites of [0]12, [0/90]6 and [0/90/45/135]3, which can be employed for detailed design and process optimization.

Experimental and theoretical simulations of a novel sustainable desalination process have been carried out. The simulated process consists of pumping seawater through a solar heater before flashing it under vacuum in an elevated chamber. The vacuum is passively created and then maintained by the hydrostatic balance between pressure inside the elevated flash chamber and outdoor atmospheric pressure. The experimental simulations were carried out using a pilot unit built to depict the proposed desalination system. Theoretical simulations were performed using a detailed computer code employing fundamental physical and thermodynamic laws to describe the separation process, complimented by experimentally based correlations to estimate physical properties of the involved species and operational parameters of the proposed system setting it apart from previous empirical desalination models. Experimental and theoretical simulation results matched well with one another, validating the developed model. Feasibility of the proposed system rapidly increased with flash temperature due to increased fresh water production and improved heat recovery. In addition, the proposed desalination system is naturally sustainable by solar radiation and gravity, making it very energy efficient.

Abstract Resin Injection Pultrusion (RIP) is a new composite manufacturing process, which combines the advantages of the conventional pultrusion process and the Resin Transfer Molding (RTM) process. It is sometimes referred to the Continuous Resin Transfer Molding (C-RTM) process. The RIP process differs from the conventional pultrusion process in that the resin is injected into an injection-die (instead of being placed in an open bath) in order to eliminate the emission of volatile organic compounds (styrene) (VOC) during processing. Based on the modeling and simulation of resin/fiber “pultrudability”, resin flow, and heat transfer and curing, a computer aided engineering tool has been developed for the purpose of process design. In this study, the fiber stack permeability and compressibility are measured and modeled, and the resin impregnation pattern and pressure distribution inside the fiber stack are obtained using numerical simulation. Conversion profiles in die heating section of the pultrusion die can also be obtained using the simulation tool. The correlation between the degree-of-cure profiles and the occurrence of blisters in the pultruded composite parts is discussed. Pulling force modeling and analysis are carried out to identify the effect on composite quality due to interface friction between the die surface and the moving resin/fiber mixture. Experimental data are used to verify the modeling and simulation results.

Abstract This paper presents an approach on the design and simulation of direct cold extrusion processes for rapid tooling with the aid of process simulation technologies. The advantage of this approach is to find problems before a metal die prototype is made, and therefore reduces the time from die design to manufacturing. A direct cold drawing die has been designed using a design approach involving the results of analytical calculations from simplified mathematical models. This design is analyzed and modified using commercial process simulation software on digital computers in this paper. This paper presents the modeling techniques involved, the analysis procedure, presentation and evaluation of these results.
