Heat and Mass Transfer in a Two‐Component Developed Turbulent Gas‐Vapor‐Droplet Flow

A calculation model is developed and a numerical study is made of the heat and mass transfer characteristics in a turbulent gas–vapor–droplet flow moving in a round tube. The model takes into account the evaporation of droplets, the diffusion of vapor into air, and the acceleration of a carrier flow. Distributions of the parameters of the two‐phase flow are obtained with respect to the tube radius for different initial concentrations of the gas phase. Heat‐ and mass‐transfer calculations are compared to the experimental and numerical works. On the whole, the evaporation of the droplets in the vapor‐gas flow leads to the intensification of heat transfer as compared to a one‐component vapor‐droplet flow and single‐phase flow of vapor.
