Experimental studies of film nozzles functioning process with the liquid film gasification

The aim of this work is to develop bench equipment and perform experimental studies of film nozzles functioning process with the liquid film gasification. The findings of the research illustrate the following parameters: the relation between the median droplet diameter and the fluid pressure at the nozzle inlet, the air pressure at the nozzle inlet, nozzle cavity pressure, fluid flow rate, air and liquid flow rate. As a result of experimental data processing, we revealed qualitative and quantitative relation between the hydro- and gasodynamic values of the gas-saturated film and modes of liquid and air supply in the cavity of a gas-liquid injector. The results obtained in designing the film nozzles with liquid film gasification will give an opportunity to significantly improve their performance.
