hi;
i want modeling multiphase flow with eulerian approach.
how to find value of particle diameter for secondray phase?
thanks for your answer.

I think your question is how to define the particle diameters in .

If am I right, you will define your particle diameter through the injection file.
The injection file is located discrete phase model (DPM)

let me know if I answered your question

If you use a single discrete phase size:

size = C_PHASE_DIAMETER(c,t);

gives the set diameter. For population balances, refer to the population balance manual.

edit: sorry, that is if you need to write a UDF and require the macro for that.
Otherwise, with eulerian mutliphase, you set the phase diameter in phases > secondary phase
