Convection also affects nucleation

WebIn this lecture we will study the phenomenon of nucleation during freezing, a process that nano- to microscale crystals called nuclei forms in the liquid phase. Nucleation is the first step of crystallization and also a kinetic process. Even when crystal-lization is thermodynamically favorable, nucleation can be slow or even unobservable under WebJun 15, 2000 · Waiting time between two successive bubbles is also a function of the wall thermal conductivity λ w. The thermal conductivity of the wall can affect heat transfer coefficients via these mechanisms, Fig. 1. The effect of variations in the wall thermal conductivity λ w on other mechanisms like enhanced convection is presumably much …
