Abstract

An experimental investigation of the interaction of a heated jet with a deflecting flow has been performed in a wind tunnel. The secondary (jet) flow is introduced at angles of 90 and 35 deg to the mainstream flow direction. Visualization studies using tufts of yarn and a carbon dioxide-water fog are reported. Temperature profiles in the interaction region are presented for blowing rates (ratio of mass flux of injected gas to mass flux of free stream) from 0.1 to 2.0 for normal injection and at blowing rates of 1.0 and 2.0 for 35 deg injection. Velocity and turbulence-intensity profiles are reported for normal injection at blowing rates of 1.0 and 2.0.
