The interaction of single vortices and vortex arrays with                       leading-edges/corners/surfaces occurs in a variety of practical                 applications and is central to determining the localized structural             loading and possible vibration of the edge, noise radiation, initial            conditions for transitional/turbulent boundary layer development                downstream of the edge, and drag on the surface of the edge.  The first         phase of this investigation considers a row of single vortices                  interacting with the leading-edge, with emphasis on the wavelength and          scale of the incident vorticity field, as an extension of preliminary           studies in the ongoing investigation.  The second phase addresses               vortex array-edge interaction.  These vortex arrays will be linked to           generation of super- and subharmonic frequency components of nonlinear          interaction phenomena in the upstream shear layer, both of which are            central features in development of unstable laminar and "turbulent"             free shear flows of finite streamwise extent.
