Flow-around Simulation of Circular Cylinder Performing Rotary Oscillations by LS-STAG Method

Authors reviewed the flow-around of circular cylinder performing a rotary oscillation at different range of angle rate amplitude and non-dimensional oscillations frequency. LS-STAG method was applied for computational simulation. Effects of reduce drag observed in experiments earlier are simulated at low-frequency rotary oscillations of the circular cylinder and at control of the airfoil wake past a circular cylinder performing high-frequency rotary oscillations which seldom reproduced numerically.
