The Research on the Performance of an Ejector-Type Anti-Splash Water Injector

In this paper, a water injector was designed to prevent water splashing. Through the analysis of the results of the single-phase flow numerical simulation, the local structure of the model which caused a higher pressure lose was optimized. Then the optimized water injector was calculated with the steady VOF model. At last some research was done on the flow state of air-water mixture impacting the wall. It obtains the distribution of the two-phase flow field and the performance parameters under various operating conditions. The total pressure loss of the optimized model has reduced by 23% compared with the initial model. Through the experiment, the reliability of the numerical simulation results is validated.
