Abstract

The article presents an improved numerical method developed for calculating turbulent flows basing on the algorithm SIMPLE, Rhie–Chow interpolation on non-staggered grids, and monotonic second and third order accurate TDV schemes. The use of high-order difference schemes for calculation of viscous flows enables achievement of significantly better resolution of the algorithm on coarse grids, which decisively affects the efficiency of two-dimensional and especially three-dimensional calculations.

湍流计算模型

摘要

本文介绍了一种基于SIMPLE算法，非交错网格上的Rhie-Chow插值以及单调的二阶和三阶精确TDV方案而开发的用于计算湍流的改进的数值方法。通过使用高阶差分方案来计算粘性流，可以在粗糙网格上显着提高算法的分辨率，从而决定性地影响二维尤其是三维计算的效率。
