摘要
从3个方向对压气机静子上游容腔进行优化设计,采用数值模拟方法对优化效果进行分析。结果表明:开槽处理会破坏流动连续性,开槽位置对流动性能的影响较大,且开槽处理方案对封严性能提升效果不明显;右端壁与左端壁两种倒圆结构在叶栅通道出口截面的总压损失系数分别下降了0.395%和0.342%;两种堆叠结构叶栅出口截面的总压损失系数分别下降2.72%和3.11%,弧形拐角的堆叠结构封严性能更优。
The upstream cavity of compressor stator is optimized from three directions,and the optimization effect is analyzed by numerical simulation.The results show that the slotting treatment may ruin the flow continuity,and the slotting position significantly affects the flow performance.In general,the sealing performance improvement effect of the slotting treatment scheme is not obvious;the total pressure loss coefficient of the right end wall and left end wall rounded structures at the outlet section of cascade passage decreases by 0.395%and 0.342%respectively;the total pressure loss coefficient of the cascade outlet section decreases by 2.72%and 3.11%respectively for the two stacked structures,and the sealing performance of the stacked structure with arc-shaped corner is better.
