In the present work a swirl chamber is employed to study the eect of ยฏuid rotation on noise reduction in supersonic jets. Fluid rotation is attained by means of a vortex chamber in which four moveable slabs are inserted. Schlieren photography is employed to visualize the ยฏow and shock structure asso
