Hi,
I am working on simulation of a circulating fluidized bed. Its assumed that the entire batch of solids are of same size (identical dp), though in reality it is not the case. Is it possible to define a particle size distribution (PSD) for such cases? Do I need to define a UDF to mention PSD? |

Hi
you can use Rosin-Rammler distribution model if you are using DPM model in fluent for inlet particles size distribution. you can eighther use UDF if Rosin-Rammler distribution model is not appropriate for your case study. |

Is it possible to implement the said model while using Eulerian-Eulerian approach?
