Quasi-steady droplet phase change in the presence of convection

Simple expressions for the rate of change of droplet mass and droplet temperature are derived for an arbitrary convective environment, under the assumptions: (1) unity Lewis number, or constant Lewis number and equal gas-phase species C/sub p/, and (2) uniform conditions on the droplet surface. Supplemented by a suitable droplet heat-flux correlation, these equations form a simple, but quite general, droplet phase change model
