3.3 Population Balance Model Setup

Following the loading of the population balance module, enable either the mixture or Eulerian multiphase model. This will allow you to activate the population balance model, where you will specify the appropriate parameters, and supply multiphase boundary conditions. These inputs are described in this chapter. Using the double-precision version of ANSYS FLUENT when solving population balance problems is highly recommended.

A limitation of the population balance model is that it can be used only on one secondary phase, even if your problem includes additional secondary phases. Note that a three-phase gas-liquid-solid case can be modeled, where the population balance model is used for the gas phase and the solid phase acts as a catalyst.
