| Popis: | This paper is devoted to the computation of turbulent flows by a Galerkin finite element method. Effects of turbulence on the mean field are taken into account by means of a k-ϵ turbulence model. The wall region is treated through wall laws and, more specifically, Reichardt's law. An inlet profile for ϵ is proposed as a numerical treatment for physically meaningless values of k and ϵ. Results obtained for a recirculating flow in a two-dimensional channel with a sudden expansion in width are presented and compared with experimental values. |
