Detailed Description

Model of Laakkonen et al. (2007). The total breakup rate is calculated by.

$C_1 \epsilon_c^{1/3} \mathrm{erfc} \left( \sqrt { C_2 \frac{\sigma}{\rho_c \epsilon_c^{2/3} (6v_i/\pi)^{5/9}} + C_3 \frac{\mu_c}{\sqrt{\rho_c \rho_d} \epsilon_c^{1/3} (6v_i/\pi)^{4/9}} } \right)$

where

$\sigma$	=	Surface tension [N/m]
	=	Volume of mother bubble i [m3]
$\epsilon_c$	=	Turbulent dissipation rate of continuous phase [m^2/s^3]
$\mu_c$	=	Molecular dynamic viscosity of liquid phase [Pa s]
$\rho_c$	=	Density of continuous phase [kg/m^3]
$\rho_d$	=	Density of disperse phase [kg/m^3]
