Hi
I am dealing with the problem simulating a circular cylinder in a wind tunnel with air (carried fluid) and solid particles(dispersed phase), the Reynolds number is around 3900 and I am done with the single-phase(air) part with importing the UDF function for the experiments inlet and boundary conditions to Ansys Fluent 18, but now I want to add three source term for my particles' motion which are momentum, k, and epsilon. So my questions are

1. How should I choose the multiphase model in Fluent, for example, DEM, DPM or ...?

2. How to add source terms to it? and the code?

3. I also want to simulate the adhesion of particles, How to achieve?

4. Is there any examples or code related to my problem that I can consult?

Thank you for helping!
