摘　　要：在二维N-S方程求解器基础上发展了考虑平面叶栅轴向密流比(AVDR)的准三维数值模拟方法,利用DLRV2叶栅实验数据对该求解器进行验证。结果表明:该求解器计算准确性较高,AVDR对叶栅性能及流场影响较大,是不能忽略的因素。本文开发的求解器求解精度较高,收敛速度快,可满足平面叶栅数值仿真要求。A quasi-three-dimensional solver which considering the AVDR based on the two-dimensional Navier-Stokes(N-S)equations was presented.The solver had been validated through the comparison between the experimental data and numerical simulation results of the subsonic cascade.The results show that the solver can reach a high calculation accuracy which prove that the AVDR is an essential input parameter when the solver simulating a cascade flow flied and performance.The solver has a high accuracy,a fast rate of convergence and could meet the demand of numerical simulation of cascade flow field.
