説明
An unstructured mesh method is presented for the non-linear k-ε model to predict the complex 3D flow filed in engineering practices. The cell-centered FVM (Finite Volume Method) is used for the discretization of the governing equations on a collocated polyhedral mesh. A strict but effective data structure is adopted for the store of the CVs (Control Volumes). It can simplify the application of hybrid polyhedral mesh. Special treatments in the discretization and the boundary conditions have been emphasized. The non-linear model in combination with the wall function approach is employed to a number of turbulent flows. For each test case, the standard k-ε model is also implemented for comparison. It is shown that the results of the simulation are in reasonable agreement with those of experiments. Moreover, the non-linear model is always able to give a more accurate result than the standard one.
