Abstract

A compact upwind difference fifth-order scheme is used to effectively and accurately perform large eddy simulations of the flow over a surface-mounted prism. Two cases of smooth and turbulent inflow conditions are compared. The results show that the highest negative mean value of the pressure coefficient on the roof and the sides is about 30% larger in the case of turbulent inflow and takes place closer to the windward edge of the prism. The predicted mean characteristics of the pressure coefficients in the turbulent case match the experimental values in terms of both magnitude and location on the roof of the prism. The effects of turbulence and the simulation duration on the peak value and its probability of non-exceedence are discussed.
