## 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.

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

where

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