Mathematical Modeling of High-Temperature Vaporization of Heterogeneous Water Drops

Research output: Contribution to journalArticle

Abstract

Experimental data on high-temperature vaporization of heterogeneous water drops, obtained by high-speed video recording, and Ansys Fluent software package were used to develop a predictive mathematical model of heat and mass transfer. An assessment was made of the influence of the key process parameter, namely, the temperature of a gaseous medium (T g = 500 – 850 K), on the integral characteristics of vaporization of homogeneous drops of water and drops of aqueous suspension containing graphite inclusions. The dependencies of complete vaporization and disintegration (due to ebullition) time on the temperature of the gases are established. The numerical modeling and experimental data are compared.
