Identifying and tracking bubbles and drops in simulations: a toolbox for obtaining sizes, lineages, and breakup and coalescence statistics
Wai Hong Ronald Chan, Michael S. Dodd, Perry L. Johnson +1
Knowledge of bubble and drop size distributions in two-phase flows is important for characterizing a wide range of phenomena, including combustor ignition, sonar communication, and…
The turbulent bubble break-up cascade. Part 2. Numerical simulations of breaking waves
Wai Hong Ronald Chan, Perry L. Johnson, Parviz Moin +1
Breaking waves generate a distribution of bubble sizes that evolves over time. Knowledge of how this distribution evolves is of practical importance for maritime and climate studie…
The turbulent bubble break-up cascade. Part 1. Theoretical developments
Wai Hong Ronald Chan, Perry Johnson, Parviz Moin
Breaking waves entrain gas beneath the surface. The wave-breaking process energizes turbulent fluctuations that break bubbles in quick succession to generate a wide range of bubble…
On the evolution of the velocity gradient tensor in transitional boundary layers
Ahmed Elnahhas, Perry L. Johnson, Adrián Lozano-Durán +1
We study the transition to turbulence from the perspective of the velocity gradient tensor dynamics. Our work is motivated by the observation of nonlinear structures emerging durin…
