Exploring attenuation of steady circumferential pressure distortion of axial flow compressor with axial fan stage 风扇级负荷对其进口总压畸变响应特性影响研究
The article analyses the influence to the generator electrode temperature from different inlet angle and inlet total pressure and the compressive angle of fluid in the situational process 本文在对等离子发生器内部纯空气流场的模拟过程中,分析了不同进口气流角、不同进口总压以及不同气流压缩角对发生器电极壁面温度的影响。
In the pseudo - time region , high efficient lu - sgs scheme was used in time - marching . cases with uniform or non - uniform inlet stagnation pressure and with or without tip - gap flow were studied . computed results showed that complex structure vortex appeared and secondary flow occurred in the flow of cascade with tip - gap 对进口总压均匀或总压周向亏损(模拟上游尾迹) 、叶尖无间隙或有间隙等三种不同情况的流场计算结果,进行对比分析发现,流场中广泛存在流动分离、分离涡以及二次流,这是引发非定常扰动的根源。
