Hi there!
I have a little problem about Rosin-Rammler distribution.

I want to obtain from Fluent the Rosin-Rammler droplet distribution by means of an injection point through DPM model. For my aim, I have several volumetric diameters and the Rosin-Rammler distribution experimentally obtained.

The injection is a Solid-Cone type, the particle type is Droplet. I set the parameters in the Injection dialogue box basing on guides, where it is also written that, when you need to obtain a droplet distribution, the Parcel Release Method must be the constant-number one (where user must add a certain value for the Particle Number in Parcel).

Now: I don't understand how Fluent works with the number of diameters d (i.e. the partition of your droplets diameter range), the number of particle stream s (that -maybe? I am not sure at all- is a prefixed number of droplet for each different parcel), and the Parcel Release Method. I noticed only that, if I click on List in the Injection box, in the text box appear initial values of the d droplet diameters repeated s times, while the number added under Particle Number in Parcel remains a mystery for me...

Please, could anyone help me to understand? Thanks
