Jacjac is on a distinguished road
Hi, I am modeling the dispersion of cough droplets in a room with two velocity inlets (velocity=1.68m/s) and one pressure outlet at 0 gauge pressure. The droplets shall be injected from a surface on the occupants' body for 0.4s.
I would like to observe the particle trajectories and get to know how many particles remain in the room. Currently running on steady-state.

I'm using the RNG k-epsilon model with a standard wall function. Plus energy equation & discrete phase modeling. May I ask if this context involves multiphase modeling and species transport?

And the results only show a streamline, how can I visualize the dispersion/concentration of the particles inside the room?

Would really appreciate it if someone could provide some advice on the setup as I got confused reading the tutorial...Thank you!

Best regards,
