Abstract
The study is to improve efficiency of three-dimensional flow simulation by parallel Collocated Cell-Centered Finite Volume Method by PC Cluster and parallel algorithm. We apply the parallel program to simulate extrusion process of the non-isothermal generalized Newtonian fluid in extrusion die. And will predict the distribution of velocity, pressure, and temperature in the three-dimensional space. We also change the number of elements of the grid and discuss its affection on efficiency of parallel simulation.In research, we adopt domain decomposition method to separate data previously, and use SPMD(Single Program Multiple Date) parallel program type to process parallel code. The data needed to exchange in simulation is achieved by MPI(Message Passing Interface). Besides, CG and GICGSTAB methods accompanied with Jacobi pre-conditioned method are used to solve linear equations.The parallel simulation is of accuracy for results obtained from sequential and parallel algorithm, are almost the same with the references. On the other hand, since the simulation results of different number of elements reveal that parallel simulation is more efficient as elements increase, it's worthwhile to adopt parallel simulation in cases with more complicated geometry.
