Abstract

The effect of cavity size and cavity density on surfaces with artificial nucleation sites

on bubble diameter and trequency of departure in pool nucleate boiling was studied by using high-speed photography and laser fiber probe. A theoretical model has been developed from the analysis of force equilibrium of a bubble on a nucleation site with dueconsideration of the mutual influence of the surrounding bubbles. Preducted results obtained from the proposed model agree satisfactorily withexperimental data.
