“…Moreover, under such conditions, the explosive disintegration of droplets occurred. We believe that when changing geometry of heating surface, the lifetimes of heterogeneous droplets established in [4,5] will reduce. Furthermore, the change of heat-exchange surface can be one of the key factors to reach the rapid elimination of heat.…”

Abstract. Using high-speed camera, the experiments were performed to research evaporation of 10 μl water droplets containing 2 mm solid inclusions in the shape of cube, when heated (up to 850 K) in combustion products of technical ethanol. Adding solid inclusions in water droplets allowed considerably decreasing (by 70%) their evaporation times. Also, the artificial irregularities (roughness and porosity) at the surfaces of solid inclusions were manufactured to increase heat transfer area. Such approach enabled to decrease evaporation times of heterogeneous liquid droplets in high-temperature gases by 40% (when comparing inclusions with artificial irregularities and smooth surface).
