Good Agreement

This paper presents an experimental investigation of throttling characteristics of a multi-wedge air inlet of a wind tunnel built for flat flow field at M = 2.5. The experiments were performed in a wind tunnel at M numbers of 2.55, 3.05 and 4.05. Results of numerical simulation of the flow in the air inlet, where air flow restriction was implemented by additional heating of the flow in the channel past the air inlet, are given for comparison. Experimental throttling characteristics are in good agreement with the values obtained from computations

Heated Jet

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.
