介绍了透平机械叶栅流动的无粘－有粘迭代计算方法。主流区无粘流动采用了边界元法计算，粘性流动区采用附面层理论的积分关系式计算。这种新的耦合解法充分发挥了边界无法计算简便的优点，未知量只在边界上，不像其它区域性数值方法那样，需对整个求解域所有节点的未知量都进行计算，从而减少了计算工作量。计算结果与实验数据进行了比较，结果表明，该方法对于透平机械叶栅内粘性流动计算，是比较简便而有效的。图３参１１ The calculation method of viscous - viscous iteration of turbine cascade flow is introduced. Boundary element method is used to calculate the non-viscous flow in the mainstream area, and the viscous flow area is calculated by the integral relation of the theory of surface layer. This new coupling method gives full play to the advantage that the boundary can not be calculated easily. The unknowns are only on the boundary. Unlike other regional numerical methods, it needs to calculate the unknowns of all nodes in the solution domain, Workload. The calculation results are compared with the experimental data. The results show that this method is simple and effective for the calculation of viscous flow in turbine cascades. Figure 3 Senate 11
