THEORETICAL MODEL FOR BUBBLE FREQUENCY IN NUCLEATE POOL BOILING INCLUDING SURFACE EFFECTS.

One of the important boiling parameters is the frequency of bubble departure. A theoretical model is formulated herein to predict the bubble frequency as a function of the nucleation cavity radius as well as the surface superheat and liquid subcooling. In this model, the time variations of the surface temperature throughout the bubble cycle are incorporated. Parametric study of the predictive equations shows that the frequency of bubble …
