EventFlow: Real‐time neuromorphic event‐driven classification of two‐phase boiling flow regimes

Droplet, EarlyView.
We present a real‐time flow regime classification framework that integrates neuromorphic event‐driven sensing with deep recurrent neural networks. Unlike traditional frame‐based approaches, our system captures sparse event streams from an event‐based camera, representing only the dynamic brightness changes at the individual pixel level.

Experimental Factors and Techniques for Pool Boiling Heat Transfer Enhancement: A Critical Review

Heat Transfer, EarlyView.
ABSTRACT This review presents a comprehensive assessment of active strategies for enhancing pool boiling heat transfer, with a focus on techniques that do not rely solely on the boiling surface modification. It examines a broad range of methodologies including fluid additives, external fields, mechanical interventions, and thermal‐geometric tuning that

Bubble Collapse in Subcooled Boiling

Bulletin of JSME, 1973
The motion of a vapor bubble in subcooled boiling was studied experimentally using slightly subcooled water, ethanol, and carbon-tetrachloride under the atmospheric pressure. The degree of subcooling ranged usually from about 2°C to 50°C, and in a few extreme cases it was extended to below 1°C. The experimental data for the collapse stage were found to
