Detailed Description

Model describing aggregation of solid particles in turbulent flows. Applicable when particles are smaller than the Kolmogorov length scale. The coalescence rate is calculated by.

$\frac{4}{3}\left(\frac{3\pi}{10}\right)^{0.5} \left(\frac{\epsilon}{\nu}\right)^{0.5}(d_i+d_j)^3$

where

	=	Diameter of particle i [m]
	=	Diameter of particle j [m]
$\nu$	=	Kinematic viscosity of continuous phase [m2/s]
$\epsilon$	=	Continuous phase turbulent dissipation rate [m2/s3]
