对于超音速混合增强，大尺度的流向涡似乎是最有利的。在超音速冲压发动机中，为了减轻巨大的气动和热负荷，需要在燃烧室壁面安装同时引入大尺度流向涡和燃料进入超音速流动的装置，这就要求它必须具有高效率地混合近壁和自由流中的流体的能力。在本研究中，我们努力阐明这种壁挂式斜坡式喷油器的混合性能。并阐明了在高马赫数流动中，超混合器型壁挂式斜板喷射器是扩展混合场的有效方法。
For supersonic mixing enhancement, large scale streamwise vortices seem to be the most advantageous. In SCRAM jet (supersonic combustion ramjet) engine, the device which introduces both the large scale streamwise vortices and fuel into supersonic flow needs to be installed on the chamber wall to alleviate the heavy aerodynamic and heat load, so that, it must have the high ability to mix the fluids in near-wall and freestream, efficiently. In the present study, we made effort to clarify the mixing performance of such wall-mounted ramp injectors. And , we clarified that Hyper-mixer type wall-mounted ramp injector is effective to expand the mixing field in high Mach number flow.
