本文应用Ｂｅａｍ－Ｗａｒｍｉｎｇ近似隐式因子分解格式以及ＭＭＬ代数湍流模型，采用拟压缩性方法求解雷诺平均拟压缩Ｎ－Ｓ方程组，对弯曲叶片压气机叶栅内的三维粘性流场进行了数值研究．结果表明，正弯曲叶栅内通道涡较直叶栅强，其诱导产生的壁面涡较弱且位于吸力面与壁端的角区内，与壁角涡接近．在正弯曲叶栅出口处，通道涡开始处于破裂前期，叶栅总损失增加。反弯曲叶栅通道涡较弱，其诱导的壁面涡很强，位于通道涡左上方，壁面涡和通道涡的有利作用，使通道涡更稳定，叶栅总损失比直叶栅和正弯曲叶栅要小．
In this paper, the Beam-Warming approximate implicit factorization format and the MML algebraic turbulence model are applied to solve the Reynolds-averaged quasi-squeezed N-S equations by the method of quasi-compressibility, and the three-dimensional viscous flow field in a curved blade compressor cascade is numerically studied . The results show that the vortices inside the positive curved cascade are stronger than the straight cascades, and the induced wall vortices are weaker and located in the corner region between the suction surface and the wall end, which is close to the corner vortex. At the exit of the crooked cascade, the passage vortex begins at the early stage of rupture and the total loss of the cascade increases. The anti-bending vortex channel vortex is weak, its induced wall vortex is very strong, which is located at the upper left of the channel vortex. The favorable effect of wall vortex and channel vortex makes the vortex channel more stable. The total loss of the cascade is less than that of the straight and positive curved cascades To be small.
