Application of the Turbulence Model to Environmental Hydraulics problem

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-a turbulence model and the revised anisotropic k-a 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.
