N2 - The kinematics of vorticity shed by a nominally two-dimensional plunging at-plate airfoil are investigated for varying Strouhal number, heave amplitude, and angle of attack. The structure of leading-edge and trailing-edge vortices (LEVs and TEVs) is described with variation of these parameters. The circulations of the LEVs and TEVs are computed, and a previously-developed scaling is applied to these values. Although the circulation values exhibit a high degree of similarity before scaling, the parameter is found to further reduce the variability of the LEVs.
