Abstract:Finally, a preliminary study on modeling micro-explosions and flash boiling was performed. These two phenomena were modeled using a bubble-droplet system. A description was formulated to predict bubble growth and was verified using experiment data. Both the breakup due to aerodynamical force and the breakup due to bubble expansion are considered. The formulated method combined with a bubble generation model was used to study effects of various parameters on the onset of micro-explosion for multicomponent droplets. The conclusions of this work agree with those in literature. A blob model was added to simulate the atomization of the spray under flash boiling conditions with a bubbly-flow in the injector nozzle, and the effect of superheat degree on spray atomization was captured.
