Испарение и "взрывное" паробразование капли жидкости с твердым непрозрачным включением в высотемпературной газовой среде

Abstract

Radiant heat flux impact on phase change conditions of a water droplet with a solid inclusion heated in a high-temperature gas flow was experimentally determined using "solid inclusion - water" system as an example. It was emphasized the evaporation from the outer surface, boiling at the internal "inclusion - water droplet" interface and explosive breakup of a heterogeneous water droplet. A full evaporation time comparison of heterogeneous droplet heated in combustion products and air at the same temperatures was carried out.
