Dynamics of droplet fragmentation in turbulence is described by the Kolmogorov-Hinze theory, but at higher concentrations common in most flows a quantitative theory is required. The authors use direct numerical simulations of turbulent multiphase flows finding that larger droplets break up absorbing energy from the flow, while smaller droplets undergo rapid oscillations and tend to coalesce releasing energy to the flow.
