Abstract
Wake of a circular cylinder subjected to acoustically driven disturbances introduced from sinusoidal slits was investigated at Reynolds number of 24,000 and 40,000. Results showed that the amplitude of the primary shedding frequency was eliminated when the forcing frequency was twice the fundamental frequency. This is attributed to the mechanism of redistribution of energy from the large coherent structures to the smaller ones. Furthermore, the introduction of three dimensional disturbances accelerated the separating shear layers which narrowed the wake and made it uniform in terms of mean velocity and reduced drag.
