Abstract

A study of high-pressure drop vaporization is conducted with emphasis placed on equilibrium at vapor-liquid interface. General frame of previous rigorous model [1] is retained but tailored for flash equilibrium calculation of vapor-liquid interfacial thermodynamics. The interfacial equilibrium model is properly validated with experimental data and the improvement of the prediction accuracy is made. The flash equilibrium calculation method is shown to be useful in predicting high-pressure droplet vaporization in the respect of solution accuracy and economy in computational cost. Vaporization of n-pentane fuel droplet quiescent in nitrogen gas is examined. High-pressure effects on the droplet vaporization suchas ambient gas solubility, property variation, transient diffusion, and multicomponent transport on the droplet vaporization are investigated and discussed.
