Various models for bubble breakage and coalescence rates are presented in the literature. These rates usually depend on physical properties, such as densities, viscosities and surface tension, and on turbulence properties, most commonly the turbulent kinetic energy dissipation rate. To calculate local bubble size distributions, also local physical properties and turbulence level should be used. This can be done via CFD (Alopaeus et al. 1999,2002 Keskinen and Majander 2000). 

In Chapter 8, we characterized the large scales of turbulence by introducing the tnrbnlent velocity Mnns and the integral scale It. These two quantities are used to quantify two key processes of turbulence, the turbulent diffusion coefficient Kt Urtcdt (equation [8.29] of Chapter 8) and the kinetic energy dissipation rate in a turbulent flow ...
