The effect of surface roughness on the wake behind circular cylinder
The influence of surface roughness on the wake behind circular cylinder has been analysed. It was shown that the roughness modifies the wake parameters. These symptoms as well as lower Karman vortices shedding frequency suggest that for rough cylinders the boundary layer separates earlier.
