HEAT AND MASS TRANSFER IN VAPORIZATION OF DROPLETS OF SOLUTIONS IN A HIGH-TEMPERATURE GAS FLOW.

problems associated with the vaporation of droplets of solutions in a flow of hot gas are analyzed, and expressions for all stages of this process (including melting and preheating), making allowance for the mutual effect of variation in the size and velocity of the droplets, the concentration of the solute in them, vapor efflux and other factors, are obtained. Expressions for variation of the fraction of solute and solvent vaporizing along the flow in the case of vaporization of an ensemble of droplets are formulated. Allowance is also made for mutual slip and time difference between the start and end of vaporization of droplets of different initial dimensions.
