Abstract
The paper describes a new technique of active control of periodic near wake behind an aerofoil with blunt base. Tangential blowing, employed only on one of the surfaces at the trailing edge, is found effective in suppressing the alternate vortex shedding, and ultimately results in a nearly symmetric and stable wake with reduced turbulence.
