摘要

The partially integrated transport modeling (PITM) method viewed as a continuous approach of hybrid RANS/LES with seamless coupling is presented. It is used for deriving a subgrid stress model based on the subgrid stresses and the dissipation rate developed in a general formulation for free flows as well as bounded flows. This model is then applied for predicting the well know turbulent channel flow as well as the periodic flow over a 2d hill which presents complex physics. As a result, it is found that the subgrid scale stress model is able to simulate the flows performed on coarse grids with satisfactory agreements with the reference data for both the velocity and the turbulent stresses and provides the detail of the flow structures.
