摘要

基于三维定常Denton程序发展了二维定常、二维非定常、三维非定常计算程序

以二维跨声压气机叶栅、三维跨声单级压气机近失速点为算例

进行确定应力耦合问题的研究.结果表明:在确定应力应用到时均方程的耦合处理中存在一些因素导致时均方程的解和非定常解的时均值有一定偏差

它们分别是空间差分离散引入的误差、黏性相关项引入的误差、掺混面处理引入的误差.在多排耦合问题中掺混面的处理方式至关重要

对耦合计算结果有较大的影响

简单的掺混面处理并不能获得理想的效果.

Abstract

Two-dimensional steady/unsteady

and three-dimensional unsteady calculation programs were developed based on three-dimensional steady Denton program. Researches on deterministic stress coupling were conducted on two cases:two-dimensional transonic compressor cascade and three-dimensional single-stages transonic compressor near stall point. It is found that

there are some deviations from time-averaged value of solution and unsteady solution of time-averaged equations when deterministic stresses are applied to coupling processing. The deviation of the coupling error originated from three sources: spatial difference discrete

viscosity correlation terms

mixing-plane processing. In multi-row coupling cases

the influences of mixing-plane are vital. It has a vital effect on the coupling calculation results. The simple mixing-plane processing can't get an ideal effect.
