Abstract
The concept of Moving Surface Boundary-layer Control (MSBC) as applied to two-dimensional airfoils is investigated through a planned numerical simulation program, complemented by wind tunnel tests and extensive flow visualization study. The moving surface was provided by rotating cylinders located at the leading edge and upper surface of the airfoil. The results suggest that the concept is quite promising and can provide a substantial increase in the lift and a delay of the stall. The maximum coefficient of lift realized was around 2. 4, approximately three times that of the base airfoil. The stall was delayed from around 10° to 48°! Application of the MSBC procedure to bluff bodies showed a remarkable decrease in the pressure drag.
