How is the drag coefficient determined?

Hi.

I would like to add particle body force in EDEM and simulate movement due to drag.

There are four models of drag coefficient (Schiller and Naumann, Morsi and Alexander, Haider & Levenspiel, Ganser), but I would like to know how the drag coefficient is determined internally.
If you have any documents, could you please share them?

Also, is there a way to give a constant drag coefficient regardless of the Re number or other conditions?

Best Regards,
