Sub-Hinze scale breakup model for high-fidelity simulation of bubbly flows

Abstract

In this reporting period, algorithms to identify bubbles and to detect bubble breakup and coalescence events in a two-phase (air/water) simulation with knowledge of the volume fraction field (spatial distribution of the air and water phases) are detailed. These algorithms are then used to characterize the evolution of the bubble size distribution in an ensemble of simulations of periodic breaking waves, including the identification of breakup and coalescence events.
