摘　　要：为改善平面叶栅风洞流场品质,获得准确度高、可靠性强的试验结果,以跨声速平面叶栅试验器为研究对象,采用数值模拟方法研究了端壁抽吸和导流尾板的组合控制方法对A,B,C,D四种不同叶型弯角平面叶栅流场品质的改善效果。研究结果表明:在叶栅前缘上下端壁进行抽吸和尾缘安装导流尾板能够有效提升叶栅进口流场的均匀性和出口流场的周期性,使得各叶栅进口马赫数偏差<0.01,C和D叶栅进口气流角偏差<0.5°,A和B叶栅进口气流角偏差<1°;该控制方法能够保证各叶栅栅后流场存在三个或三个以上相邻满足周期性要求的连续通道。In order to improve the flow field quality of transonic linear cascade and obtain highly accurate and reliable test results,numerical simulation were carried out for a transonic linear cascade test device to investigate the improvement effect of a method combined endwall aspiration and tailboard on the flow field quality of A,B,C,D four different camber linear cascades.The results show that the aspiration on the upper and lower side walls of the leading edge of cascade and tailboard installed on the trailing edge could remarkably improve the inflow uniformity and outflow periodicity of cascades.The difference between the inlet Mach number of each cascade and the set value is less than 0.01,the inflow angle deviation of cascade C and D is no more than 0.5°,the inflow angle deviation of cascade A and B is less than 1°.There are more than three outflow channels to meet periodic requirements by the control method.
