Abstract
The interaction between vapor bubbles resulting from phase change in pool boiling was simulated through a two-phase lattice Boltzmann method. Two heated plates with constant heat flux were used to serve as the nucleate sites. The effects of wall wettability were examined. In doing so, three types of surface were taken into account, i.e. the hydrophilic surface, neutral surface and hydrophobic surface. It has been shown that the effects of wettability on the interaction between bubbles are significant in terms of the bubble mergence as well as the rate of heat transfer. In addition, the influence of the separation between the heated plates was also checked.
