摘要
讨论了紊流数值模拟的发展历史、现状及真挚比较了各类紊流模型的优缺点及适用范围，并对特殊效应（曲率、近壁区）的处理作了介绍和评述，为了提高模型的预报能力，多重尺度和非线性模型正应用于工程计算。随着计算机的发展，大涡和直接数值模拟也取得了一些研究成果。
In this paper numerical simulation of turbulence is reviewed and commented briefly. A variety of turbulent models are compared including effects of curvature and near wall. To improve prediction ability, multi scale model and non linear model are being applied to numerical calculation. With the development of the computer, some results on large eddy simulation and direct numerical simulation are achieved.
