✦ Synopsis

The time-dependent temperature distribution within a droplet with internal heat generation and surface vaporization has been studied using a finite-difference numerical method. The heat transfer equations were nondimensionalized for computer calculations, and solutions were obtained for cases when the initial temperature is equal to and different from the surface temperature. Variation of droplet radius due to vaporization was included in the assumed model, and radial temperature distributions, relative to the surface temperature, were calculated under the assumption of constant surface temperature. Representative results are given as temperature and radius histories for a wide range of dimensionless variables. The results are applicable when surface temperature changes with time provided that the rate of change is small compared to the initial temperature transient due to heat generation.
