Hydraulics of aerated flows: qui pro quo?

H Chanson - Journal of Hydraulic Research, 2013 - Taylor & Francis
In turbulent free-surface flows, the deformation of the surface leads to air bubble entrainment
and droplet projections when the turbulent shear stress is greater than the surface tension …

A multi-field two-fluid concept for transitions between different scales of interfacial structures

A polydisperse two‐fluid model for surf zone bubble simulation

G Ma, F Shi, JT Kirby - Journal of Geophysical Research …, 2011 - Wiley Online Library
Wave breaking in the surf zone entrains large volumes of air bubbles into the water column,
forming a two‐phase bubbly flow field. Numerical study of bubbly flow is largely restricted by …

Spherical bubble dynamics in a bubbly medium using an Euler–Lagrange model
