Laser texturing of silicon surface to enhance nucleate pool boiling heat transfer
Applied Thermal Engineering, 2021The surface modification is one of the most promising and discussed methods to improve the boiling performance. To date there are a lot of techniques to modify a heating surface, but the search for the optimal, simple and reliable one is still an actual ...

Nucleate boiling heat transfer and critical heat flux (CHF) from micro-pit surfaces
International Journal of Heat and Mass Transfer, 2020This paper studies pool boiling enhancement on the micro-pit surfaces. Microscale pits fabricated on plain surface are able to reduce boiling incipience superheat, and improve both nucleate boiling heat transfer coefficient and critical heat flux (CHF ...

Nucleate boiling on nanostructured surfaces using molecular dynamics simulations
International journal of thermal sciences, 2020Nanostructures have significant impacts on incipient nucleation time and onset temperature during nucleate boiling. This study compares three types of surfaces, namely smooth, concave structured, and convex structured to investigate the mechanism of ...

During nucleate boiling, a thin liquid film (microlayer) is formed beneath a boiling bubble when the bubble undergoes rapid growth/expansion. The linear distribution of the microlayer has been previously confirmed, and its crest shape has been observed ...

Surface Nanobubbles Nucleate Liquid Boiling
Langmuir, 2018Surface nanobubbles have been presumed to lead to the experimental observation that liquid boiling often occurs at a much lower supersaturation than expected, yet no qualitative theory exists to explain how they participate in the process. Here, we report through a simple theoretical analysis on how the metastable nanobubbles nucleate the liquid-to ...

Visualization-based nucleate boiling heat flux quantification using machine learning
International Journal of Heat and Mass Transfer, 2019Processes involving complex phenomena are ubiquitous in nature and industry, many of which are difficult to simulate computationally. Nucleate boiling heat transfer, for instance, has numerous practical applications, while the film boiling is an ...
