Droplet Heating and Evaporation: Hydrodynamic, Kinetic and Molecular Dynamics Models

摘要

Some recently developed approaches to the hydrodynamic, kinetic and molecular dynamic modelling of mono- and multi-component droplet heating and evaporation are discussed. New approaches to taking into account the effect of the moving boundary during droplet evaporation on droplet heating for mono- and multi-component droplets are summarised. A simplified model for multi-component droplet heating and evaporation, based on the analytical solution to the species diffusion equation inside droplets, is described. A quasi-discrete model for heating and evaporation of complex multi-component hydrocarbon fuel droplets, and its application to modelling the heating and evaporation of realistic Diesel and gasoline fuel droplets are described. A new kinetic algorithm, taking into account the effect of inelastic collisions, is reviewed. The results of applications of molecular dynamics simulations to study the evaporation of n-dodecane droplets are described.
