Abstract : The vorticity shedding characteristics in attached and separated regions were investigated over three configurations: a backward facing circular arc, an ellipse at angle of attack, and a pitching airfoil. Two component velocity measurements were obtained and emphasis was concentrated on the separation region, the free-shear layer and the wake downstream of the bodies. Two inviscid vortex models were also developed to predict the flow behavior. Keywords: Vorticity; Unsteady Aerodynamics; Separated Flow.
