Abstract
A fast responding Pressure-Sensitive Paint (PSP) using polymer/ceramic binder and image capturing technique called Phase Lock Method were used to visualize the unsteady pressure distributions on a capsule-shaped body undergoing the pitching motion. In addition, schlieren visualization using high-speed video camera was used to take a picture around the flowfield of the model, together with pitch angle measurement using a potentiometer. As a result, the strength and the location of vortices behind the capsule varies depending on the direction of the oscillating motion, and the base pressure distributions are related to the dynamic motion of the vortices from the edge of the capsule.
