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

Exploration (Beijing)
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

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).

Improvement of the subcooled boiling model using a new net vapor generation correlation inferred from artificial neural networks to predict the void fraction profiles in the vertical channel

Nuclear Engineering and Technology, 2022
In the one-dimensional thermal-hydraulic (TH) codes, a subcooled boiling model to predict the void fraction profiles in a vertical channel consists of wall heat flux partitioning, the vapor condensation rate, the bubbly-to-slug flow transition criterion,
