27.1. Coulaloglou and Tavlarides Breakage

The breakage frequency is given by

(27–1)

where and are constants with values of 0.00481 and 0.08, respectively, is the surface tension, is the volume fraction of the dispersed phase, is the turbulence energy dissipation rate of the primary phase, and is the density of the dispersed phase [1].

Important:  Make sure you first enable beta feature access, as described in Introduction.

Refer to Enabling the Population Balance Model in the Fluent User's Guide to learn how to enable the population balance model. Enable the Breakage Kernel option and select tavlarides-model from the Frequency drop-down list. Enter the desired Surface Tension in the Surface Tension for Population Balance dialog box.
