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.
