高负荷状态下压气机平面叶栅试验流场品质通常不佳,需借助调控手段提升流场品质以确保试验数据可用。基于亚声速平面叶栅风洞设计了可调尾板的被动方案,研究了尾板安装角对大攻角状态下叶栅流场品质及性能的影响,并与之前研究的上端壁抽吸主动方案的结果进行对比。结果表明:可调尾板通过改变叶栅出口静压分布来调节叶栅进口流场品质。随着尾板安装角减小,靠近上尾板的叶栅出口静压减小,靠近下尾板的叶栅出口静压增大,叶栅流场品质得到提升,然而,若减小尾板安装角超过一定限度,栅前流场均匀性和出口流场周期性将会下降,因此,为达到最佳流场品质,需控制尾板安装角在特定临界值;由于尾板对出口气流的隔离作用,叶栅出气角周期性最好,周期性指数在1以内。上端壁抽吸对叶栅进口流场均匀性的改善比可调尾板更好。由于两种手段的调控机理和流场品质差异,可调尾板调控后叶栅出气角比上端壁抽吸偏小2°左右,损失偏大约0.02;两者的静压比和叶片表面等熵马赫数差异较小。
The flow quality of the linear cascade tests for compressor airfoils is always poor under high-load conditions
it is necessary to improve flow quality of linear cascade by adjusting methods to ensure the availability of test data. A passive control scheme of adjustable tailboard was designed based on a subsonic linear cascade wind tunnel. The effect of tailboard angle on flow quality and performance of cascade was investigated
and compared with the results of active control scheme of upper end-wall suction previously studied. The results indicate that the tailboards adjust the flow quality by changing the exit static pressure distribution. As the tailboard angle decreases
the exit static pressure near the upper tailboard decreases while it increases near the lower tailboard
leading to an improvement in the cascade flow quality. However
if the tailboard angle is decreased beyond a certain limit
the uniformity of the inflow and the periodicity of the outflow will decline. Therefore
to achieve the best overall flow quality
the tailboard angle needs to be controlled within a specific critical range. And the outlet flow angle shows the best periodicity due to the isolating effect of tailboard
with a periodicity index less than one. The flow quality of cascade declines when the tailboard angle is over the critical value. The improvement of inflow quality of cascade by upper end wall suction is better than that of tailboard. Due to the difference of control mechanism and flow quality between these two methods
the outlet flow angle of cascade adjusted by tailboard is about 2° smaller than that of upper end wall suction
and the loss is about 0.02 larger than that of upper end wall suction. The difference of static pressure ratio and distribution of isentropic Mach number between the two methods is small.
