Abstract:
The internal flow mainly studied the flow coefficient, liquid film thickness and gas core radius, and analyzed the internal flow field. A small amount of research has involved the impingement of internal and external nozzles, the amplitude and frequency of the liquid film surface wave. There have been many researches on the external liquid film flow and spray characteristics of liquid-liquid injector. The flow patterns of the internal and external liquid films under different working conditions and structural parameters were observed. A few scholars used theoretical methods to analyze the mechanism of liquid film breaking. The research on the spray characteristics is mainly to obtain the variation of spray cone angle, breaking length, liquid film oscillation frequency, etc., and further study the variation of SMD, droplet velocity and mixing characteristics and so on
