Enhancing efficiency of using water due to explosive breakup of liquid drop

Abstract

Using high-speed video recording, the experiments were performed to research quantitative characteristics of explosive breakup phenomenon of 5-15 [mu]l water droplets containing 2•2•1 mm and 2•2•2 mm solid inclusions, when heated in a tube furnace at temperatures of 1070-1370 K. Experimental results report number and size of the droplets detached during explosive breakup. We show that the fragmentation of liquid layer covering solid particles facilitates the increase the evaporation surface area 15-fold versus the initial surface area of a drop.
