摘要

基于三维定常Denton程序发展了非定常、非线性谐波法计算程序

以三维单级、多级跨声速压气机计算为例

通过详细对比非定常和非线性谐波法得到的确定应力(DS)场

验证了非线性谐波法具有建模精度较高的优点的同时

也分析了影响建模精度的5个误差来源.结果表明:非线性谐波法进行确定应力建模时随着谐波阶次的增多

确定应力的数值趋于一极限值

表现出“谐波收敛性”;在算例中考虑前两阶谐波是效益-费用比较高的方案.

Abstract

Three-dimensional unsteady

nonlinear harmonic method calculation procedures were developed based on three-dimensional Denton steady solver. The high-modeling-precision advantage of nonlinear harmonic method was validated by contrast the deterministic stresses(DS) field solved with unsteady and nonlinear harmonic method for two three-dimensional single-stage and multi-stage transonic compressor simulation cases

and the five sources of modeling error were analyzed. Results show that with the increase of harmonic orders

the value of deterministic stress constantly goes to a limit

presenting the characteristic of “harmonic convergence”. Only first two harmonic components taken into account was the best choice in the simulation cases because of its high benefit-cost ratio.
