One type of parallel injection method with ramp injector was selected and the effects of oblique shock impingement on supersonic mixing layer generated from the ramp had been studied. The patterns of shock waves in the numerical schlieren image agreed with experimental results in schlieren photograph. Comparisons of static pressure on the wall surface and spatial Pitot pressure distributions showed good agreement qualitatively. Numerical results captured the structures of flow field clearly, which were generating process of a pair of streamwise vortices and vortical roll-up of the jet. The oblique shocks had some effects on the flow field, which made injectant gas lift off from wall surface and increased intensity of streamwise vortices. According to these results, it could be said that the CFD (Computational Fluid Dynamics) code used in this study was useful for investigation of fuel-air mixing in supersonic flow field with parallel injection. From the numerical results mentioned above, it was confirmed that the streamwise vortices generated by ramp injector and interaction between mixing field and oblique shocks were key factors for enhancement of fuel-air mixing in ram/scramjet combustor.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
