Abstract

The effects of free-stream turbulence and of sinusoidal free-stream pulsations of controlled frequencies and amplitudes on the periodic wake of a circular cylinder are investigated experimentally by employing hot-wire and smoke visualization techniques. In addition, the effects of cylinder yaw and mild favorable and adverse pressure gradients on the vortex shedding mechanism have been explored.
