Prognosis Model for Investigating the Evaporation of Water Droplets

Research output: Contribution to journalArticle

Abstract

A model of heat and mass transfer in a homogeneous water droplet and in a water droplet with a solid inclusion has been developed with the use of the Ansys Fluent package for investigating the high-temperature evaporation of such droplets. The influence of the size of a water droplet, the thickness of its vapor shell, the thermal diffusivity of the water in the droplet, the size of an inclusion in it, and the temperature of the gas medium surrounding the droplet on the time of its existence was determined. The mechanisms of heating homogeneous and inhomogeneous water droplets were investigated with and without regard for the emission of heat by the water-vapor layer. Approximation expressions for simulation of the evaporation of homogeneous and inhomogeneous water droplets have been obtained.
