Help, energy sources.
 
Hi
I want to add mass source, momentum source , energy source and species source into fluid .
One material(one species) was adding to fluid, its temperature is T, specific heat at constant pressure is Cp, enthalpy at reference temperature is h0. The mass source is a(kg/m^3).
I have a question, the energy source is?
Thank you.

You can use fluent multiphase model or discrete phase (lagrangian approach) to add particles in the fluid stream. Then add heat/mass exchange in it as well.
You can use the UDF function DEFINE_DPM_SOURCE if you want your own laws for heat, mass and momentum transfer.
