“…Transverse injection from a wall orifice is one of the simplest and most promising configurations to enhance the mixing process between the injectant and air in supersonic flows [3], and it attracts an increasing attention since the early sixties [4], especially on some scramjet powered vehicles [5]. Huang and Yan [6] provided a survey on the transverse injection from four aspects, namely the jet-to-crossflow pressure ratio, the injector configuration, the injector number and the injection angle, and the two-dimensional transverse jet flow field was optimized by the non-dominated sorting genetic algorithm (NSGA II) coupled with the Kriging surrogate model [7].…”
