基于并行BICGSTAB的不可压流场计算方法
摘要
Abstract
Incompressible flows are prevalent in daily life and engineering applications.With the continuous expansion of numerical simulation scales,CFD algorithms increasingly emphasize parallel computing.This paper utilizes the SIMPLE algorithm to solve incompressible flow.We developed a parallel BICGSTAB matrix solver based on the MPI framework to address the large sparse matrices in the algorithm.Finally,the feasibility and accuracy of the parallel algorithm are validated using the steady lid-driven cavity flow and unsteady flow around cylinder test cases.关键词
