Puffing/micro-explosion of two closely spaced composite droplets in tandem: Experimental results and modelling

The results of the experimental and theoretical investigations mutual effect on their puffing/micro-explosion droplets in a flow, using an example two closely spaced tandem, are presented. It is shown that time to (?p) lead droplet always shorter than downstream droplet, difference between them decreases with increasing distance divided by initial diameters (2Rd0). ?p both increases Rd0. interpreted terms previously developed model for fuel/water puffing/micro-explosion, based assumptions water sub-droplet located centre fuel this process triggered when temperature at water/fuel interface reaches nucleation temperature. interaction taken into account via modifications Nusselt Sherwood numbers these numerical calculations. Both experimentally observed predicted values increase They be longer droplets. differences close differences.
