Hi everybody
I use Ansys fluent and I want to solve a multiphase flow (liquid and gas containing solid) with euilerian method. is it accurate that I use no-slip wall boundary condition for solid (granular phase)? If I want to change no slip boundary condition, how much do I take specularity coefficient?
Thanks in advance.
Use this forum it can help you. Good luck.

This condition is under discussion. Some researchers argues that no-slip generates a ill-posed system, mean while others have good results using that. But rarely they are studying the same problem under the same conditions, so is controversy. I advice you read more about that to have a better vision about your problem
