UDF to drag coefficient and non newtonian fluid

Hi all!
Have you anyone wrote an UDF to calculate the drag coefficient on lagrangian particles (DPM) for non-newtonian fluid? The DEFINE_DRAG_FORCE macro returns a value of 18*Re*CD/24. Althogh the Reynolds number is different for Newtonian and Non Newtonian fluid. I have tried changed the Reynolds number when returning the drag force, but it did not work. Anyone can help? |
