摘要
利用NUMECA软件对某跨音速压缩机形成了一套可靠的数值计算模型。设计了一种周向槽处理机匣,计算表明处理机匣可明显扩大压缩机稳定工作范围,并通过对转子内部流场模拟分析出原因。
A dependable numerical model was built by the NUMECA software on a high-loaded transonic compressor.Then a circumferential grooved casing treatment was designed,and the numerical simulation research showed that it can obviously enlarge the stable working range of compressor.And the reason was analyzed with internal flow field simulation analysis of rotor.
