摘要
从叶轮机械转动坐标系中的三维、可压、湍流、Ｒｅｙｎｏｌｄｓ平均Ｎ－Ｓ方程组出发，用Ｂａｌｄ－ｗｉｎ－Ｌｏｍａｘ湍流模式使方程组闭合；结合有限体积离散并采用隐式矢通量分裂技术；求解了西德宇航院（ＤＦＶＬＲ）的单级跨音速压气机转子内的三维湍流流场。计算结果可分辨出该转子内三维流场的细微结构、激波的空间曲面；得到马蹄涡、通道涡、尾迹涡和角涡的形态及其发展，流场的三维性非常明显。
A Reynolds averaged Navier Stokes equation is solved for three dimensional flowfield inside a transonic compressor rotor,which has been experimentally investigated at the DFVLR.The numerical solution is based on implicit flux vector splitting scheme,and Baldwin Lomax turbulence model is used for the turbulence modeling.Based on the numerical results, the detailed flowfield structures,the secondary flows,and vortex development in the blade passage have been given.
