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

E3S 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

Enhancing Pool Boiling Heat Transfer by Structured Surfaces– A Lattice Boltzmann Study [PDF]

Journal of Applied Fluid Mechanics, 2022
The structured surface-enhanced pool boiling process and associated heat transfer enhancement characteristics are numerically investigated by using the pseudopotential multiphase flow lattice Boltzmann (LB) model coupled finite difference method (FDM ...

A study on transition process to MEB by limiting boiling space

Journal 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).

Modelling of pool boiling on the structured surfaces using Lattice Boltzmann method [PDF]

E3S Web of Conferences, 2023
The process of boiling on spatially structured surfaces is simulated by a hybrid model based on Lattice Boltzmann Method and heat transfer equation. The model permits to study heat transfer at boiling in a wide range of surface superheats for different ...

On the modelling of the transition between contact-line and microlayer evaporation regimes in nucleate boiling

Journal of Fluid Mechanics, 2021
Formation of a microlayer in nucleate boiling results in substantial changes to the heat-transfer dynamics of the process, and establishing a criterion to distinguish between the microlayer and contact-line regimes encountered is necessary to obtain a ...

Predicting Conduction Heat Flux through Macrolayer in Nucleate Pool Boiling

Energies, 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.
