Boiling in nanopores through localized Joule heating: Transition between nucleate and film boiling
The transition from nucleate to film boiling on micro/nanotextured surfaces is of crucial importance in a number of practical applications, where it needs to be avoided to enable safe and efficient heat transfer.

Direct numerical simulation of nucleate boiling in micro-layer regime [PDF]
The physical mechanisms associated with the evolution of a micro-layer beneath a bubble and the transition between contact line and micro-layer regimes are investigated with fully resolved numerical simulations, in the framework of nucleate pool boiling.

Bubble Behavior and Heat Transfer in Quasi-Steady Pool Boiling in Microgravity [PDF]
Pool boiling of degassed FC-72 on a plane plate heater has been studied experimentally in microgravity. A quasi-steady heating method is adopted, in which the heating voltage is controlled to increase exponentially with time.

Nucleate Pool Boiling Regimes Of Power Electronics Cooling
The boiling curve of refrigerant FK-649 at a saturation temperature of 36°C is experimentally determined for nucleate pool boiling on the baseplate of an IGBT power module. The nucleate pool boiling curve can be subdivided in three zones. At low heat fluxes (lower than 20 kW/m²), partial nucleate boiling occurs. This zone is followed by fully developed

A Novel Role of Three Dimensional Graphene Foam to Prevent Heater Failure during Boiling [PDF]
We report a novel boiling heat transfer (NBHT) in reduced graphene oxide (RGO) suspended in water (RGO colloid) near critical heat flux (CHF), which is traditionally the dangerous limitation of nucleate boiling heat transfer because of heater failure ...
