EVAPORATION OF FOG UNDER CONDITIONS OF CONSTANT VOLUME OR CONSTANT PRESSURE

In a previous theoretical study, the evaporation of a preheated polydi sperse droplet fog had been investigated at constant volume, either wi th a constant undersaturation of the vapor or at a constant temperatur e. In the present work, evaporation of a fog at constant volume or pre ssure is analyzed. The phenomenon that is described - a sharp retardat ion of fog evaporation when the initial heating corresponds exactly to equality of the heat supplied and the heat of the phase transition (o r the phenomenon of ''anomalous thermal stability of fog'') - is also manifested, the same as with constant undersaturation of the vapor.
