Abstract: A model of thermal relaxation in the flow of a hot vapor–gas mixture and cold water drops is presented. The cooling of vapor and gas during heating and evaporation of droplets was numerically simulated. Approximation expressions are obtained for the cooling time of vapor and gas in a given temperature range depending on the initial droplet radius, the weight fraction of droplets, and the initial composition of the vapor–gas mixture.

Keywords: thermal relaxation, numerical simulation, heating and evaporation of droplets, cooling time of vapor and gas.
