• 論文の詳細を見る

• A numerical technique for investigating the mixing characteristics of supersonic turbulent flow with different gas species, in which a two-equation turbulence model was employed, was presented in the first report. This report clarifies the effect of inlet flow profiles on the mixing phenomena by adopting distributed flow profiles obtained for a supersonic wedge-shaped nozzle outlet as the inlet boundary conditions for the mixing calculations. The general conclusion is that mixing layers with distributed inlet flow profiles are thicker than those with uniform profiles. Furthermore, the relationships of the growth rates of mixing layers with distributed inlet flow profiles to the changes in the velocity ratios and density ratios are similar to those of layers with uniform profiles.
