Abstract:
We consider fully turbulent flow around a cylinder mounted on a flat plate. We performed a highly resolved Large Eddy Simulation using zonally refined grids around the cylinder and a fully turbulent inflow condition. The flow is characterized by strongly non-equilibrium near wall velocity profiles which deviate from the equilibrium law of the wall. We assess the prediction of wall shear stresses in those regions which has an impact on wall modeling and prediction of erosion and scour development.
