Heat Transfer to Single Drops of a Nonazeotropic Fluorocarbon Mixture Evaporating in Water

Visualization study of evaporation of single n-pentane drops in water

“…Consult, for example, Shimizu and Mori (1989) for further discussion of this aspect of the problem. The A T* dependence of the present interest is of course a "real" one that can still be recognized when a reasonable definition of the temperature difference is used.…”

“…Thus, to develop a model describing the heat transfer to and the evaporation in such bubbles, it is important to know the flow field around the bubbles, particularly the field in the vicinity of the liquid/liquid interface which must preferentially cover the lower part of the surface of each of the bubbles. Most of the theoretical models proposed so far assume an irrotational flow or a boundary layer flow over the whole surface of each bubble, and consequently they deal with a convective heat transfer across a thin thermal boundary layer clinging to the surface (Vuong and Sadhal, 1989;Shimizu and Mori, 1989; and several_ earlier works cited there). Recently Mori and Ehara (1992 a, b), suspecting that the liquid/liquid interface on each bubble is adjacent mostly to a wake rather than a boundary layer, proposed models describing the heat transfer that takes place exclusively through the wake to the liquid/liquid interface located at the rear surface of each bubble.…”
