Abstract
The present study deals with the numerical study of the mixing process in a 2D supersonic ejector. The performance parameters such as momentum flux, degree of mixing and stagnation pressure loss are used to analyse mixing process. The evolution of the kinetic energy of turbulence is also observed. The investigation is carried out on a conventional 2D supersonic ejector and on a 2D supersonic ejector equipped with wall slot injectors along the mixing chamber. The performance parameters show a significant mixing enhancement when transverse micro-jets are used.
