K－ε模型在复杂管流中的模拟计算

Numerical Simulation of Complicated Pipe Flow with K-ε Model

本文对复杂管流中的湍流问题采用了ｋ－ε模型进行模拟计算。对于复杂边界问题采用了阶梯型网格近似，取得了较好的结果。文中给出了两例复杂管流的计算算例，说明了Ｋ－ε模型具有很强的适应性和稳定性。

Tn this paper,turbulence in a complicated pipe is simulated by using the k-ε model.The ladder-like mesh approximation is used to solve the problem of com- plicated boundary with the favorable result of numerical simulation .Two compu- tational examples are given to validate the strong adaptability and stability of k-ε model.
