The results of functionality testing of this model for heat and mass transfer between two parallel plates are reviewed. New results of the application of the model to the analysis of a twocomponent (n-dodecane and p-dipropylbenzene) droplet’s heating and evaporation in a high pressure background gas (nitrogen) in Diesel engine-like conditions are presented. As in the case of the previously developed similar models, the model used in the analysis is based on the introduction of the kinetic region in the immediate vicinity of the droplets and the hydrodynamic region. The model is tested for the analysis of heating and evaporation of a droplet with initial radius and temperature equal to 5 μm and 300 K, respectively, immersed into gas with temperatures 1000 K and 700 K for several mixtures of n-dodecane and p-dipropylbenzene. It is shown that the increase in mass fraction of p-dipropylbenzene and kinetic effects lead to the increase in predicted droplet evaporation time. It is shown that the kinetic effects increase with increasing gas temperature and molar fraction of p-dipropylbenzene.
