Sustained and Enhanced Nucleate Boiling Using Hierarchical Architectures at Large Superheats. [PDF]
Sustained nucleate boiling and Leidenfrost delay are critical for thermal and energy industries. Leveraging vapor buffer and reducing water‐hammer pressure, this study realizes the enhancement of nucleate boiling and postponement of Leidenfrost by rationally designing and developing hierarchical nano–micro structured surfaces. Besides, AI technology is

Moving contact lines in a pure-vapor atmosphere: a singularity-free description in the sole framework of classical physics [PDF]
We here show that, even in the absence of "regularizing" microscopic effects (viz. slip at the wall or the disjoining pressure/precursor films), no singularities in fact arise for a moving contact line surrounded by the pure vapor of the liquid ...

Predicting Conduction Heat Flux through Macrolayer in Nucleate Pool Boiling
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.

Comparative analysis of BLEVE mechanical energy and overpressure modelling [PDF]
The mechanical effects of a BLEVE are overpressure and ejection of fragments. Although fragments reach much longer distances, peak overpressure can be very strong over a certain area.
