用于粘性可压缩流动数值计算的SIMPLE方法
A SIMPLE ALGORITHM FOR VISCOUS COMPRESSIBLE FLOWS
-
摘要: 对SIMPLE方法加以推广,使之适用于可压缩粘性流动的数值计算。采用非交错网格技术,推出三维任意曲线坐标系下可压缩形式SIMPLE方法的计算方程。对亚音速、跨音速及超音速等5个流场进行了数值计算并与有关文献及实验数据进行比较。Abstract: Based on the SIMPLE algorithm,a three-dimensional pressure-based finite volume calculation procedure for compressible flows in arbitrary-shaped domains is presented.The pressure is evaluated by the compressible form of the pressure-correction equation of SIMPLE algorithm.The present method is used to compute a number of cases ranging from subsonic flows to supersonic flows.The computed results are in good agreement with the available published experimental and computed data.
