A PIV study of blockage ratio effects on flow over a confined circular cylinder at low Reynolds numbers

The present study examines the flow over a circular cylinder confined between two parallel walls in the lateral direction using a Particle Image Velocimetry (PIV) method. The experiment covers five blockage ratios ( β ) of 1/6, 1/5, 1/3, 1/2 and 3/5, respectively, at Reynolds numbers ( Re ) up to 13...
