Numerical simulation of nucleate pool boiling under high pressure using an initial micro-layer thickness model

open access: goldCase Studies in Thermal Engineering, 2022
Micro-layer evaporation is one of the main phase change mechanisms in nucleate pool boiling. However, the influence of pressure on micro-layer evaporation remains unclarified.

Predicting Conduction Heat Flux through Macrolayer in Nucleate Pool Boiling [PDF]

open access: goldEnergies, 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.

Physical Model of a Single Bubble Growth during Nucleate Pool Boiling [PDF]

open access: goldFluids, 2022
A simplified physical model of a single bubble growth during nucleate pool boiling was developed. The model was able to correlate the experimentally observed data of the bubble’s growth time and its radius evolution with the use of the appropriate input ...

A unifying criterion of the boiling crisis [PDF]

open access: yesNature Communications, 2023
We reveal and justify, both theoretically and experimentally, the existence of a unifying criterion of the boiling crisis. This criterion emerges from an instability in the near-wall interactions of bubbles, which can be described as a percolation ...
