Abstract: 

Positioning a splitter plate at the certain line in the wake of the cylinder is an effective method to reduce the acoustic drag force and lift force. The simulations of the flow past the only stationary D-section cylinder at different Reynolds number 400, 500, 600, 700, and 45000 are included here to have a study on the mechanisms of the D-section cylinder in the flow. Two-dimensional unsteady laminar flow over a semi-circular cylinder with a prescribed flexible foil was investigated numerically. The mechanisms of the single fixed D-section cylinder in the flow and the propelled foil will be studied and the interaction effect on both of cylinder and foil will be explored by setting the optimal parameters as different foil undulation frequency and gaps between them.
