EXPERIMENTS ON THE FLOW ABOUT A YAWED CIRCULAR CYLINDER

Experiments were performed to evaluate the influence of yaw angle on circular cylinder pressure drag and wake characteristics in the range of free-stream Reynolds numbers 5000 to 20,000. It was found that the transition in the wake from laminar to turbulent motion was significantly promoted as the angle of yaw increased. As a result, wake properties such as base pressure and shear wave or transition frequency do not obey the independence principle which requires that properties be dependent only on the normal component of the freestream conditions.
