Hi everyone
Regarding particle size distribution in FLUENT the only available functions are Rosin Rameler (RR) and Uniform distribution. So what if I have my own distribution or even my own injection with a unique condition (e.g velocity, PSD,...). I was wondering if this can be introduce to FLUENT using a file injection?? If yes, how am I suppose to do that? what about the use of UDF? Can anyone explain this to me since I have a very vague vision of this. Your prompt suggestions are most appreciated ![]() |

Thank you so much for your reply. This is a nice trick but do you think it is handy when you have a a very wide distribution. I mean hundreds of diameters??? How can this be done by a UDF?? Have you got any idea? |

And select the one which is the best compromise between the computational time and accuracy. |

Is this "Bin" defined by "Number of diameters" in the injection properties dialogue box? If yes the only particle size distribution which includes this feature is Rosin Ramler. So if I select RR for my injections again the overall distribution will be RR? am I right?

Fluent only offers Rosin-Rammler distribution. Log-normal distribution can also be used but it is not available in Fluent. |
