Abstract
To explore the effects of wettability and surface tension on heat transfer in sliding bubble dynamics, we investigated the manner in which the dynamics of bubble sliding and heat transfer over a heated surface depend on the degree of wettability and the surface tension. Using the volume-of-fluid (VOF) method, the interface of the dispersed phase was tracked in terms of the local volume fraction. The obtained simulation results were consistent with those obtained from experimental studies. Although the heat transfer obtained when bubbles slid freely across the surface were strongly correlated with the skin-friction coefficient, deformability rather than skin friction dominated the heat transfer of bubbles adhering to the surface. The heat transfer rate increased with bubble deformability.
