摘要

从雷诺应力模型出发

通过求解雷诺平均N-S方程组获得三维湍流流场的数值解。计算中比较了多种湍流模式

并进行了相应的流场计算。本文完成了两个典型算例。从算例1的计算结果与实验值比较中发现:采用雷诺应力模型(RSM)计算的三维流场比采用k-ε模型更贴近实验值;算例2采用了RSM模型及三维非结构网格

对一典型内流问题进行了三维流场计算。算例的数值实践表明:采用雷诺应力模型可以有效的计算各向异性的湍流流场;另外

发展非结构网格有助于模拟壁面附近的流动

并节省计算机内存。

Abstract

Based on the Reynolds Stress Model

the three-dimensional flow field was numerically simulated using the Reynolds averaged N-S system equations.The flow fields were calculated and compared with the results of several turbulent models.Two typical examples were presented.Comparing numerical results to experimental data

we can find that the numerical results with the Reynolds Stress Model (RSM) are closer to the experimental data than with the Standard k-ε model.Besides

detail flow field of a typical problem was simulated with RSM using three-dimensional unstructured grids.Numerical results show that the Reynolds Stress Model could simulate turbulence anisotropic behavior of the complex three-dimensional flow field.
