Default coefficient of restitution for solid particles
Posts: n/a
Hi everyone! I'm trying to model solid particles in continuous phase, I want to include the volume fraction of solid that's why I use Eulerian-Eulerian approach. For the details of solid particles, I entered zero for coefficient of restitution because I want it to stick when it hits the wall. Is that restitution for particle to particle or particle to wall or both?If it is also for particle to wall, how can it hit the wall if the only available wall boundary conditions in Eu-Eu are no slip and free slip. Because the no/free slip conditions use zero normal wall velocity so does it mean it will not hit the wall? I'm a little bit confused. Please help me! Thanks a lot guys!

I think that the restitution coefficient you are talking about is particle-particle one because you must be required to mention slip or no slip for solid phase at the wall.

Hope it helps.
