摘要
采用多块点对点网格生成技术,生成螺旋桨流场空间计算网格。针对不同前进比,分别求解Eu ler和NS方程对螺旋桨流场进行数值模拟,并与实验结果进行了对比分析。研究发现无粘和有粘的计算结果均接近于实验结果,因此基于Eu ler方程的流场数值模拟更适用于工程设计。
The propeller flows at different advance ratios are numerically simulated.The computations predict the rotational flow by solving Euler and NS equations respectively,using finite volume method and multi block,point-to-point grids.The comparison and analysis show that the numerical results,both the inviscid and viscous ones,go well with experimental results.Since the Euler results satisfy the accuracy demand in engineering already,the Euler solver is choose to more applicable to meet the time efficient in design period.
