Characterization of pool boiling mechanisms over micro-patterned surfaces using PIV
TLDR
In this paper, an innovative analysis of the boiling process from micro-patterned surfaces is proposed, which combines image post-processing with PIV measurements, and the characteristic bubbles velocity obtained by PIV measurement evidences that the optimal pattern which balances the positive effect of increasing the parcel of liquid evaporation and the negative effect of the horizontal coalescence also allows a more stable vertical bubble velocity, thus removing the vapor from the surface.About:

Nucleation site interaction in pool boiling on the artificial surface
Lei Zhang,Masahiro Shoji +1 more
TL;DR: In this article, the authors investigated the physical mechanisms of nucleation site interaction in pool boiling and found that three significant effect factors, hydrodynamic interaction between bubbles, thermal interaction between nucleation sites, and horizontal and declining bubble coalescences, determined the intensity, competition and dominance relations of these three factors.

How does surface wettability influence nucleate boiling
TL;DR: In this article, a new approach of nucleation mechanism is established to clarify the nexus between the surface wettability and the nucleate boiling heat transfer, and the concept of macro-and micro-contact angles is introduced to explain the observed phenomenon.
