为精简附面层抽吸结构、提升吸附式压气机的工程应用性，提出将串列叶栅技术与端壁附面层抽吸技术相结合的主/被动流动联合控制技术。以某多级高负荷吸附式压气机末级静子作为研究对象，借助数值模拟的方法，探讨串列叶栅技术、端壁附面层抽吸技术以及主/被动流动联合控制技术对原型扩压叶栅内部流场结构及气动损失的影响。研究结果表明，主/被动流动联合控制技术结合了两种流动控制技术的优势，对原型高负荷扩压叶栅内部复杂流动的控制效果明显优于单一流动控制技术，通过应用更少的附面层抽吸量，有效地抑制了角区失速的促发，缓解了二维叶型分离流动，叶栅出口参数沿展向分布更为均匀，当端壁附面层抽吸总量为进口流量的0.90%时，总压损失降低了59%。

In order to simplify the aspirated structure and improve the engineering appliance of the aspirated compressor,a compound flow control method,composed of tandem cascade and endwall suction technology,is proposed. Effects of applying tandem cascade,endwall suction and compound flow control method on the flow structures and aerodynamic loss of a highly loaded outlet vane are investigated by numerical simulations. As a result,the control effect of the compound flow control method is advantageous over the single flow control method,the corner stall is depressed and the two-dimensional flow separation is alleviated effectively by using a smaller aspirated flow rate,moreover,the outlet flow parameters turn more evenly,the total pressure loss is reduced by 59% when 0.90% of inlet mass flow is sucked away.
