紊流模型理论的发展与现状

The Development and Present Condition of the Turbulent Flow Model Theory

讨论了紊流数值模拟的发展历史、现状和趋势,比较了各类紊流模型的优缺点和适用范围。多重尺度和非线性模型正逐步应用于工程计算;大涡和直接数值模拟也取得了一些研究成果。

This paper discusses the development process, present condition and trend of the turbulent flow numerical simulation,.compares the advantage and shortcoming of different kinds of turbulent flow model. Multiple scale problems and nonlinear models are gradually applied to engineering computation. Some research results of the large eddy simulation and direct numerical simulation are obtained.
