    Abstract: An experimental investigation was made of the unsteady pressure on a circular cylinder in a free stream of constant and oscillating velocity. Consideration of possible resonant coupling mechanisms between the Karman vortex street fluctuations and free-stream velocity oscillations showed such coupling to, be insignificant. The frequency of the vortex street fluctuations scales with the mean velocity for high frequency (30 to 50 Hz at mean velocity of 40 fps) oscillation of the free stream.
