摘要

使用X热线热膜技术

在设计流量下研究了3个不同进口导叶预旋角的时序效应对离心压缩机非定常流场的影响.结果表明:时序效应会影响离心压缩机叶轮出口和扩压器进口的流场

该影响将随着叶轮出口的距离增加而减弱.对应不同的进口导叶预旋角

时序效应对离心压缩机非定常流场的影响有所不同.对于不同的导叶时序位置

进口导叶0°预旋角下集平均径向速度发生变化的流动区域范围最大

-20°预旋角下的其次

20°预旋角下的最小.不同的导叶时序位置的集平均绝对气流角在较大范围内存在差别

其中0°预旋角下集平均绝对气流最大变化角为1.6°

20°预旋角下的最大变化角为0.9°

-20°预旋角下的最大变化角为1.2°.不同导叶时序位置的扩压器进口时均绝对气流角在0°预旋角下相差1.3°

在20°预旋角下相差不足0.5°

在-20°预旋角下相差0.84°.

Abstract

The stator clocking effect on the flow filed at three inlet guide vanes(IGV)prewhirl angles are experimentally investigated under design condition in a centrifugal compressor by X-type hot-wire/hot-film anemometry. The results show that stator clocking enables to changes the rotor discharge and the downstream stator inlet flow. The influence weakens when the distance from the rotor outlet increases. The magnitude of the clocking effect is different for different inlet guide vanes prewhirl angles. The flow range where the ensemble-averaged radial velocity changes at different stator clocking positions gets the widest under 0° prewhirl angle

next under -20°

then under 20°. The absolute flow angle changes evidently at different clocking positions. At different clocking positions

the maximum variations of unsteady absolute flow angles are respectively 1.6

0.9 and 1.2 degree under 0°

20° and -20° prewhirl angles. The variations of time-average absolute flow angle at different clocking positions are respectively 1.3

less than 0.5 and 0.84 degree under 0°

20° and -20° prewhirl angles.
