droplet concentration by Species Transport
 

Ciao!

In a manuscript, I saw they plot some droplet consecrations which is obtained by computing a transport equation for C (concentration) in Species Transport in fluent.
I want to define a tracer gas, which provides a picture about how the contaminant released and have been ransported/spreaded with the air motion in the room. I already knows that species option in fluent has been used for some combustion reaction and I have no idea how can I solve the transport equation for droplet.
Do anyone know how it is possible?

Simply do not turn on volumetric reaction

Hi and thanks for your reply. could you please give me more details about the setting?
What is more convenient for the part mixture material? should I use mixture temperature?
For the boundary layer setting, as far as I check, I can set maximum unity value for the mass fraction. what does it mean?
how can I have the particle/droplet concentration in a certain points/surfaces?
