Abstract
Breakup models were developed for the Euler–Lagrange framework taking breakup by turbulence, drag, and rotation into account. The modeling includes the post breakup treatment and a time lag between successive breakup processes. The prediction of the size distribution based on this four-way coupled Eulerian–Lagrangian approach delivers a reasonable agreement with experimental data.
