摘要
以某型航空发动机叶轮机为研究对象,采用了周期性边界条件和spalart-allmaras湍流计算模型,通过数值模拟,研究了进口扰动波对二维叶栅气动性能的影响,结果表明:随着扰动振幅和扰动频率的增大,叶栅通道的总压损失系数均变大。
A turbomachinery of the aero engine is researched. And the spalart-allmaras turbulent model is used for numerical simulation of the flow field in the two-dimensional cascades. The results show that the coefficent of total pressure loss becomes more large with the incresse of the perturbation amplitude and frequency.
