Low Reynolds Number Drag Law - UDF
 

Hi guys,

I am doing a DPM project in Fluent. I am looking at how many particles a given geometry can trap. The particles are sand particles (10micron - 100micron) in seawater.

Does any one have a UDF that calculates the drag force on particles in low Re-Number flow? I have very little experience with this and therefore I would need som guidance if I were to make one myself...
