Spray characteristics of unlike impinging jets

Because theoretical research on unlike impinging injectors is lacking, a comprehensive model for unlike impinging is proposed for the study of spray characteristics. In this model, the influences of the intermiscibility of working fluids on surface energy conversion and viscous dissipation are involved. Experiments for the impingement of the two types of working fluids are conducted and compared with theoretical estimations, and the results exhibit good agreement. The effects of surface tension and the mass diffusion coefficient on sheet characteristics (shape, thickness, and velocity distribution) are also investigated.
