Abstract
This paper presented a numerical analysis method for one-dimensional sparse storage structures to compress the large sparse matrix formed by the numerical discrete of the pressure Poisson equation with the numerical discrete projection algorithm,and only stored the non-zero elements.At the same time,it used the BiCGSTAB algorithm with optimized properties to solve the pressure Poisson equation to significantly improve the computational efficiency.Under the same initial conditions,it used the SOR(successive over relaxation) iteration method by Fortran90 to solve the linear equations obtained by numerical discretization of the pressure Poisson equation.The result shows that the BiCGSTAB algorithm based on compressed storage has obvious advantages in solving sparse linear equations.The algorithm is fast,efficient and reliable.关键词
