WebFeb 15, 2024 · This difference is explained by the presence of a certain level of turbulence in the mixing layer of the real jet, as compared to the completely laminar model implied in the computations. The supersonic core lengths calculated from the experimental data obtained by the Pitot tubes with diameters up to 1.1/0.8 mm coincide with each other. WebDec 24, 2015 · By employing impeller to advance the instability position of jet flow field, the mixing efficiency was increased by 20–30 % (Ducci and Yianneskis 2007). The experiments done by McLaughilin et al. revealed that an effective way to promote mixing was to utilize glow discharge excitation system in a supersonic mixing layer. By producing a glow ...
