Hi everyone,

For my master thesis, I'm currently getting into CFD and all of its amazing capabilities. I'm working on STAR-CCM+ but do not have any experience with the program.
The idea is to build an experimental set-up where PIV is possible, which would take place in a cube of about 1m x 1m x 1m. PIV requires the air to be seeded with tracer particles, in this case DEHS.

The question is the following: will these tracer particles be spread out homogeneously throughout the cube? I've attached the geometry as a picture.

Therefore I have to model this two-phase flow in the software however I don't know what model to use and how to implement the flow of the aerosols and check whether the mixture is homogeneous etc.

I'd like to implement time dependent boundary conditions where I'd close the in- and outlet to keep the particles in the room.

Any help would be greatly appreciated!
Thanks in advance!!
Greets,
