| Abstract: | Shock-wave structure due to collision of a hypersonic main jet with a transversely injected side jet and flowfield model for good mixing characteristics were investigated solving two-dimensional complete Navier-Stokes equations. Two flowfield models were considered: (i) upper boundary consists of a wall, named the "confined flow", and (ii) the upper wall was removed making the flowfield as "unconfined". In confined flow the side sonicjet, associated with upper and lower walls, produced a number of non-uniform reflected shock waves and acted as a blockage for the hypersonic main jet resulting in a large subsonic region. To get the supersonic mixing flowfield, we made the flowfield unconfined and increased the Mach number of side jet from M= 1.0 to M=2.0. The computer program was verified by the experimental results on the flow pattern of an air jet in a duct with abrupt area enlargement. |
