Abstract
The paper briefly presents the development and application of a turbulence depth-averaged two- equation closure model, stemed from the revised version of k-w model and symbolised by k and W (depth-averaged turbulent kinetic energy and depth-averaged turbulence vorticity fluctuation parameters). In the model, the depth-integrated partial differential k - and w -equations were solved together with depth-integrated mean flow equations in order to determine depth-averaged turbulence eddy viscosity and diffusivity as well as other variables. Two steady examples and one unsteady example were carried out to investigate and apply the established model. They are: 1). The side jet with temp
