主　　题：mathematical roughness function,sublayer of laminar flow blowing and suction mechanism drag reduction respond time 

摘      要：The flow past a circular cylinder and airfoil with varying mathematical roughness function are numerically simulated. A new model about blowing and suction is constructed by using the concept of mathematical roughness function. The flow field and the drag are investigated through this new model. By the numerical study about bluff body, some conclusions are drawn to reduce the drag.
