Abstract
Experimental and theoretical investigations were conducted for the vaporization of a single alcohol droplet in air with various degrees of humidity. Experimental results show that the vaporization of a volatile alcohol, such as methanol and ethanol, is accompanied by the simultaneous condensation of water vapor on the droplet surface and its subsequent diffusion into the droplet interior such that the associated condensation heat release greatly facilitates the initial gasification rate of alcohol. However, for alcohols which are less volatile, or for liquids which are not miscible with water, atmospheric moisture has practically no effect on the droplet gasification rate. Theoretical results substantiate the above observation. © 1987.
