Investigation of Parameters Influencing the Deflection of a Thick Wall Jet by a Thin Wall Jet Coflowing over a Rounded Corner

Abstract

Recent investigations proved the compatibility of the Circulation Control and the Upper Surface Blowing Concepts. This static investigation is a follow-up to determine what combinations of geometric and pneumatic variables produce an effective deflection of a thick wall jet by a thin wall jet exhausting over a rounded corner. Static pressure distributions over the corner indicate that maximum deflections of the thick wall jet occur when a high average suction is distributed over the surface of the corner. Using a large corner radius, locating the source of the thick wall jet somewhat upstream from the corner and the thin wall jet source, and using a high aspect ratio thick wall jet are geometric means of producing this type of pressure distribution.
