| Abstract | A brief review of some publications on computation of incompressible turbulent flow in complex geometries is given. A 2D finite volume method for the calculation of turbulent flow in general curvilinear coordinates is described. This method is based on a staggered grid arrangement and the contravariant flux components are chosen as primitive variables. Turbulence is modeled by the standard k-" model with wall functions. Applications of this method to a variety of flows are presented. The results of computations are compared with experimental data and other numerical solutions and are found to be satisfactory. 1 Introduction Solving incompressible turbulent flows using a boundary-fitted coordinate system is an important technique in CFD. It permits an easy and accurate implementation of boundary conditions and makes the computation of flows in complex geometries possible. For this purpose two different approaches can be adopted. The first approach is a complete transformation of the N... |
