Abstract

Abstract:

The mixing characteristics of air streams in a dump duct with two side 2D supersonic inlets 90° apart have been investigated by experiment and numerical simulation in this paper. Results indicate: (1) The main reasons for the loss of the total pressure at the mixing duct are the impingment and vortex motion of the air streams in the duct. The flow field is uniformed gradually along the mixing duct, except that at the region of injection.
