The effects of normal surface suction and blowing on the Strouhal frequencies in vortex shedding over porous square cylinders was analyzed numerically The general characteristics determined were (1) an initial increase followed by a decreasing behavior in the Strouhal frequency with increasing suction velocity and (2) a decrease in the Strouhal frequency with increasing blowing velocity. The numerical results were compared to existing analytical predictions, yielding fairly close agreement.
