摘要

为了探索进气道/发动机一体化设计方法

发展了一种压气机与进气畸变耦合计算的方法.首先从压气机基准流场雷诺平均Navier-Stokes(RANS)仿真结果中提取压气机叶片对气流的作用力

建立压气机全通道体积力模型.再将压气机体积力模型加入到流体计算软件CFX中

实现插板进气畸变与压气机的耦合计算.与实验结果对比表明:压气机体积力模型能有效模拟压气机与上游畸变流场的耦合作用

相比传统的全通道RANS计算能减少近2个数量级的计算网格数.

Abstract

In order to explore the integrated design method of inlet/engine

a simulation method was developed to analyze the coupled calculation of inlet distortion and compressor. First

a full-passage body force model for compressor was built by using blade force extracted from Reynolds average Navier-Stokes (RANS) simulation results. Second

by adding the compressor body force model into the CFX software

the flat baffle inlet distortion coupled with compressor was simulated and analyzed. Comparing the simulation results with experimental results

the compressor body force model could simulate the strong coupling interactions between the compressor and the upstream distortion flow field. And the body force model could reduce almost two magnitudes of mesh numbers compared with the compressor full-passage RANS model.
