采用Ｓｐｅｚｉａｌｅ的非线性ｋ－ε模型计算了平面叶栅内的紊流流动，并且与标准的ｋ－ε模型的计算结果作了对比，表明非线性模型同样可以应用于具有周期性边界条件的复杂流动，在紊流量的计算结果上表现出了明显的各向异性。
The non-linear k-ε model of Speziale was used to calculate the turbulent flow in the plane cascade and compared with the standard k-ε model. The results show that the nonlinear model can also be applied to the complex with periodic boundary conditions The flow shows obvious anisotropy in the calculation of turbulent flow.
