On pool boiling at microscale level: The effect of a cavity and heat conduction in the heated wall

In this paper a numerical study of pool boiling at microscale level is presented using the lattice Boltzmann approach. Applying various geometrical configurations for the heated plate, the bubble departure diameter and release period are determined from the simulation results as the function of heat flux, wettability and gravity. Finally the evolution of the temperature field of the heated plate is studied.
