| Research Abstract |
Mixing of fuel injected into supersonic internal flow with a pseudo-shock wave, which appears in the combustor of a dual-mode ramjet engine, is significantly and non-isotropically improved. In order to clarify the mechanism of this mixing enhancement, injectant concentration and velocity distributions were measured using a particle image velocimetry (PIV)and a planar laser-induced fluorescence (PLIF), respectively. In addition, numerical simulations were carried out to understand the flowfield. As a result, we found that the pseudo-shock wave produced strong turbulence near the wall and it enhanced mixing of the jet.
