用正交曲线坐标系下的粘性层方程求解湍流分离流动

A SOLUTION OF TURBULENT SEPERATED FLOW IN THE ORTHOGONAL CURVILINEAR COORDINATES WITH VISCOUS-LAYER MODEL

本文应用粘性层模型,采用贴体的正交曲线网格,对湍流流动进行了计算.计算结果表明,不论有无分离,该方法都能较准确地模拟.

The present study deals with the numerical calculation of the turbulent flow around airfoils in the orthogonal curvilinear coordinate system with the aid of the so-called viscous-layer model.The calculation results, comparing with the experiment results, show that the viscous-layer model is efficient and convenient to simulate nonseparated and seperated flows.
