Abstract:

Experimental computational and theoretical work was designed to investigate the unsteady separation phenomenon. The experimental investigations used qualitative methods allowing a full characterization of the forcing functions and planforms capable of producing and controlling unsteady flow separations. For select test conditions the characterizations were to employ quantification of the unsteady flow phenomena. In addition, the theoretical and numerical aspects were closely coordinated to study the potential applications in high performance flight vehicles.
