A set of large eddy simulations for the free surface backward facing step (FSBFS) are carried out to study wave formation behind step. The volume-of-fluid ghost fluid method is employed capture surface. Previous studies have indicated that physics depend on draught-based Froude number (Fr). For small Fr, rear face (transom) becomes wet, while separates smoothly from transom. Close a critical Fr...

Large-eddy simulations of free surface flow over bed-mounted square bars are performed for laminar, transitional and turbulent flows at constant Froude number. Two different bar spacings selected corresponding to k-type (reattaching flow) roughness, respectively. The validated with experimental data convincing agreement between simulation measurement is obtained in terms water elevations stream...
