Combustion of a liquid fuel droplet in the process of non-equilibrium surface evaporation

Mathematical models for individual droplets combustion incorporated in polydispersed mixtures modeling are usually based on the assumptions of the equilibrium character of phase transitions even for unsteady-state evaporation regimes. Comparison of theoretical and experimental data shows that this assumption being undoubtedly valid for large droplets and flat surfaces brings to essential errors for small droplets. The aim of the study is to develop a mathematical model for the non-equilibrium combustion of a single droplet surrounded by a diffusion microflame. The model will take into account non-equilibrium phase transitions.
