通过详细对比其定常、非定常和非线性谐波法的计算结果

包括确定应力场和叶片表面速度分布等

验证了非线性谐波法具有建模精度较高的优点的同时

也分析了该方法的不足

包括一些难以克服的主要误差来源

以及计算时间较长等弱点;并指出了掺混面处理对于非线性谐波法的重要性.

Abstract

A two-dimensional steady

unsteady and nonlinear harmonic method(NHM) RANScode was developed based on Denton steady code.Then the code was used to simulate a two-dimensional transonic compressor cascade by the above three methods and the results were compared on deterministic stress fields

blade surface velocity and other aspects.The comparison indicates that NHMpresents high precision on modeling deterministic stresses and mixing-plane treating plays an important role in the simulations.The shortcomings of NHMwere also discussed

including main unconquerable origins of modeling error and long computational time.
