Detailed Description

Model of Laakkonen et al. (2006). The total breakup rate is calculated by.

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


\( \sigma \) = Surface tension [N/m]
\( v_i \) = Volume of mother bubble i [m]
\( \epsilon_c \) = Turbulent dissipation rate of continuous phase [m2/s3]
\( \mu_c \) = Molecular dynamic viscosity of liquid phase [Pa s]
\( \rho_c \) = Density of continuous phase [kg/m3]
\( \rho_d \) = Density of disperse phase [kg/m3]
