Enhancement of critical heat flux in nucleate boiling of nanofluids: a state-of-art review [PDF]

open access: yesNanoscale Research Letters, 2011
Nanofluids (suspensions of nanometer-sized particles in base fluids) have recently been shown to have nucleate boiling critical heat flux (CHF) far superior to that of the pure base fluid.

Sustained and Enhanced Nucleate Boiling Using Hierarchical Architectures at Large Superheats [PDF]

open access: yesExploration
Droplet boiling is a common occurrence in many industrial processes, but it can be hindered by the Leidenfrost effect. The Leidenfrost point (LP), defined as the temperature at which an accumulated and stagnant vapor forms between the liquid and the ...

The pulsating nature of bubble boiling of subcooled water flow during cooling of a metal heater [PDF]

open access: yesE3S Web of Conferences, 2021
This paper presents the results of an experimental study of the subcooled water flow boiling on the surface of a metal rod 12 mm in diameter. As a result of the rapid heat release that occurs when an electric current is pulsed through a metal heater, the

A study on transition process to MEB by limiting boiling space

open access: yesJournal of Thermal Science and Technology, 2021
The study of microbubble emission boiling (MEB) is gaining popularity because it violently emits several microbubbles during subcooled pool boiling, for which the heat flux is greater than the critical heat flux (CHF).

Predicting Conduction Heat Flux through Macrolayer in Nucleate Pool Boiling

open access: yesEnergies, 2021
In the current work, the heat flux in nucleate pool boiling has been predicted using the macrolayer and latent heat evaporation model. The wall superheat (ΔT) and macrolayer thickness (δ) are the parameters considered for predicting the heat flux.
