研究了将Navier-Stokes方程中黏性项简化为黏性彻体力的建模方法,并将该模型加入已有的计算流体力学(CFD)程序中,实现了用三维欧拉方程加黏性彻体力模型快速模拟叶轮机三维非定常流动的方法.使用该方法对进气周向总压畸变条件下的某双级压气机非定常流场进行了模拟,并与雷诺平均的Navier-Stokes(RANS)程序的计算结果进行了对比,结果表明,基于黏性彻体力模型的方法能以很少的计算资源给出与RANS模拟基本相当的计算结果. In this paper, the modeling method of simplifying the viscosity term in Navier-Stokes equation to viscous total force is studied. The model is added to the existing computational fluid dynamics (CFD) program, and the three-dimensional Euler equation This method is used to simulate the unsteady flow field of a two-stage compressor under the circumstance of total pressure distortion in the inlet air, and is compared with the Reynolds-averaged Navier-Stokes (RANS ) Are compared. The results show that the method based on the viscous and sturdy model can give the calculation results that are basically equivalent to the RANS simulation with few computational resources.
