Description

Large Eddy Simulation (LES) is a promising method for the prediction and study of turbulence, but it requires a grid resolution that scales as the square of the Reynolds number in attached boundary layers. In the present paper the inner region of the boundary layer is modeled in a statistical sense using a Reynolds Averaged Navier-Stokes (RANS) model. The purpose of the present study is to investigate and improve the combination of LES/RANS in boundary layers. The test case chosen is fully developed channel flow, which, despite its geometrical simplicity, is a very challenging flow for LES
