Abstract

Numerical results are presented for an n-hexane droplet initially at 300 K evaporating into nitrogen, for ambient pressures, Px, 1-100 atm and ambient temperatures, Tx, 500-1500 K. At low Px (<30 atm), droplet lifetimes predicted with or without liquid-phase gas solubility are very close. At high Px, the model neglecting solubility either underestimates the droplet lifetime (low Tx) or breaks down by failing to predict vapor-liquid equilibria (high Tx). At high enough Px, heat-up is extremely important throughout the entire droplet lifetime. In a fuel rich environment, relatively low Tx, and high Tx, substantial condensation occurs before the onset of vaporization.
