用虚拟压缩方法求解不可压缩流动
Numerical Solution of the Incompressible Navier-Stokes Equations with Artificial Compressibility Method
【摘要】 本文详细介绍了虚拟压缩方法的基础理论,通过引入已经成熟的求解可压缩方法的数值离散格式,研制了一套具有宽广应用范围的数值模拟软件。对已知的几个经典问题的初步计算,得到了比较满意的结果。
【Abstract】 The method of artificial compressibility is introduced in this paper.Combined with the finite difference method in the compressible problem,a program is made out to solve the Incompressible Navier Stokes Equations.A series of classical examples are simulated and compared with experiments.The results are satisfactory.
