An analysis of multicomponent fuel droplet vaporization under elevated pressures and temperatures is made, with particular emphasis on the liquid phase transfer and high pressure phenomena. A mathematical model is proposed, which consists of a gas phase with variable properties, liquid phase with an effective diffusivity and phase equilibrium at the gas-liquid boundary. Some calculation results' are given for pentane-octane mixtures. It is shown that differences between the relative evaporation rates of different species are smaller when ambient pressure is increased. It is also shown that the potential for this particular miscible multicomponent droplet to undergo micro-explosions decreases as the pressure increases.
