摘要
对湍流模型应用于模拟预报工程附近的流场特征与物质掺混输运扩散规律的研究进行了综述，分析了国内外各种湍流模型的研究现状及发展趋势；同时就湍流模型求解环境水力学问题提出了笔者的观点，并对零方程模型、单方程模型、双方程ｋ－ε模型及修正的各向异性ｋ－ε模型、雷诺应力模型、代数应力模型、低雷诺数流动模型、双流体模型及湍流高级模拟等模型的各自特点进行了讨论。
This paper summarizes application of the turbulence model to study the characteristic of flow field and the pattern of mass mixing diffusion transportation. The research present situation and new development trend on the turbulence model are analysed in detail. Moreover, the viewpoint on environmental hydraulics problem solved by turbulence model is put forward, and the traits of zero-equation turbulence model, one-equation turbulence model, two-equation k-Ε turbulence model and the revised anisotropic k-Ε turbulence model, the Reynolds stress model, the algebraic Reynolds stress model, the low-Reynolds flow model and the senior simulation of turbulence flow are discussed.
