Abstract : Mean pressure measurements around three yawed circular cylinders were made to determine the effect of changes in yaw angle and freestream velocity on the average pressure coefficient, and the drag coefficient. The existence of four distinct types of circumferential pressure distributions, subcritical, transitional, supercritical, and asymmetric, were confirmed along with the appropriateness of scaling on a streamwise Reynolds number, based on the freestream velocity and the fluid path length along the cylinder in the streamwise direction.
