Abstract
The evaporation of a drop of volatile liquid in high-temperature surroundings is analyzed in terms of the rate of heat transfer. Transfer of heat by mass transfer and by radiation as well as by conduction is taken into account for a pseudostationary and steady state without convection. The flow of cold vapor to the surroundings during evaporation requires that a considerable amount of heat conducted inward be used to warm vapor moving outward. This waylaying of heat energy results in a significant decrease in the apparent rate of heat transfer as measured by the rate of evaporation. Applications of the theoretical results to evaporation and combustion are discussed, and an empirical treatment for cases of free and forced convection is indicated.
