Detailed Description

Model of Lehr et al. (2002). The breakup rate is calculated by.

$0.5 d_j^{*^{5/3}} \mathrm{exp}\left(-\frac{\sqrt{2}}{d_j^{*^{3}}}\right) \frac{6}{\pi^{3/2}d_i^{*^{3}}} \mathrm{exp} \left( - \frac{9}{4}\left[\mathrm{ln}\left(2^{2/5} d_i^{*}\right)\right]^{2} \right) \left( 1 + \mathrm{erf} \left[ \frac{3}{2}\mathrm{ln} \left(2^{1/15} d_j^{*}\right) \right] \right)^{-1} \frac{1}{L^{3}T}$

with the time scale

$T = \left(\frac{\sigma}{\rho_c}\right)^{2/5} \frac{1}{\epsilon_c^{3/5}}$

the dimensionless diameter

$d^{*} = \frac{d}{L}$

and the length scale

$L = \left(\frac{\sigma}{\rho_c}\right)^{3/5} \frac{1}{\epsilon_c^{2/5}}$

$\rho_c$	=	Density of continuous phase [kg/m3]
$\sigma$	=	Surface tension [N/m]
$\epsilon_c$	=	Continuous phase turbulent dissipation rate [m2/s3]
	=	Diameter of daughter bubble i [m]
	=	Diameter of mother bubble j [m]
