Journal ArticleDOI
Pool boiling characteristics of nano-fluids
TL;DR: In this paper, the authors investigated the role of transient conduction in pool boiling and concluded that the change of surface characteristics during boiling due to trapped particles on the surface is the cause for the shift of the boiling characteristics in the negative direction.
