Characteristic Features of Boiling and Vaporization of Heterogeneous Liquid Drops in High-Temperature Gaseous Medium

Abstract

The effect of radiative heat flux on the conditions of heating and phase transformation of heterogeneous water drops in a stream of high-temperature gases corresponding to a group of modern chemical and energy technologies, especially thermal purification of water, is determined with reference to opaque graphite inclusion–water system. It is demonstrated that heterogeneous water drops can not only vaporize from the outer (free) surface, but also boil at the inner interfaces and even burst. The time of occurrence (complete vaporization) of a heterogeneous drop at identical temperatures in combustion products and in air is compared.
