arXiv Preprint Shows Capillary Power Retains Finite Negative Residual in Bubble Turbulence

The preprint demonstrates that near-contact interactions create a distinct small-scale energy pathway in bubble turbulence, overturning the closed-capillary assumption. Evidence comes from spectral budget analysis in direct numerical simulations. This has direct implications for foam and emulsion modeling accuracy.

Next steps include laboratory validation using high-speed imaging of controlled bubble swarms and incorporation of the extended transfer term into subgrid models. If confirmed, the adjustment could improve predictive accuracy for environmental bubble plumes and industrial aeration systems within five years.

⚡ Prediction

Montessori: Laboratory bubble-swarm experiments will measure a 10-20% small-scale dissipation excess by 2028.
