摘要

The cavities behaviour for nucleation on roughened surface is numerically studied for the entire ebullition cycle based on a phase-change lattice Boltzmann method without introducing any artificial disturbances. The bubble departure diameter, departure frequency (BRF) and total boiling heat flux of an ebullition cycle are explored. It is demonstrated that cavity with circular groove shows the best performance for NBHT in terms of the averaged heat flux and BRF. The departure of the first bubble in triangular groove is the fastest while that in re-entrant groove is the slowest.
