Effect of the Heating Scheme of Heterogeneous Droplets on the Characteristics of Micro-Explosion Fragmentation

Abstract

According to experimental results, a comparison of sizes of child droplets after micro-explosion fragmentation of water–Diesel droplets is conducted. Convective, conductive, or radiative heat exchange dominated in each experiment. The temperature of the medium and the relative volume concentration of the flammable liquid are varied in the ranges from 100–450°С and from 10–90 vol %. The ratios of the sizes of the droplets formed to the sizes of the original ones are established. The conditions are shown under which it is possible to increase the total surface area of evaporation of a liquid by tenfold or more using the micro-explosion of droplets.
