该文用压力相关法与人工压缩法求解三维稳态不可压粘性流动过程,并进行比较.每种方法都用来预测圆形弯管三维、层流流动.每种方法的数值结果都与已求得的实验结果及以前使用多种网格数值方法获得的结果进行了比较.该文同时揭示了每种方法的优点和缺点.
In this paper, three-dimensional steady-state incompressible viscous flow is solved by pressure correlation method and artificial compression method, and each method is used to predict three-dimensional circular flow pipe laminar flow.The numerical results of each method are consistent with The experimental results obtained are compared with the results obtained by the previous methods using a variety of grid numerical methods.The article also reveals the advantages and disadvantages of each method.
