Summary:Title screen
This research work presents the results of the modeling of heat transfer processes before micro-explosion of two-liquid droplets under intense heating in a gaseous medium. The work relies on three formulations that differ in the disintegration criteria: (i) overheating of the water/fuel interface above the temperature of the onset of explosive boiling; (ii) the critical radius of the bubble before disintegration; (iii) overpressure in the vapor film. The droplet disintegration delay times were determined as functions of the temperature of the external gaseous medium, the initial droplet size and the components concentration. The theoretical values of the droplet disintegration delay times were compared with those recorded in the experiments. The limits of applicability of the three approaches to the estimation of the delay times of micro-explosion of two-liquid droplets were singled out.
