COLLAPSE OF A BUBBLE OF VAPOR IN AN IMMISCIBLE LIQUID
Abstrakt
The collapse of a bubble of saturated vapor rising through a cold continuous immiscible liquid is investigated analytically and the results are compared with experimental data from the literature. It is shown that the internal resistance to heat flow, ignored by other investigators, is significant. Further it is shown that the interfacial temperature during collapse is not a function of angular distance from the stagnation point but only a function of the properties of the two fluids. Due to the vapor occupying the major portion of the volume of the bubble, even up to 95% condensation, a simplified expression for bubble collapse is possible.
