Hi, in FLUENT 6.3, you can set the granular temperature at the boundary condition in the boundary condition panel, selecting the corresnponding granular phase. In the phases panel, when you...

Hi, yes, you can specify the granular temperature at the boundary conditions. For the inlet, it should be in the tab where you specify the boundary condition for the particle phase. Btw, you...

What has to be "high" is the granular temperature imposed at the boundary. The value of 10 seems pretty high to me, but something in the range 0.1 - 1 (m/s)^2 might work. If...

OK, I suspected it was a 2D case with a common inlet for both the phases, because I met a similar behaviour when I computed risers. First of all, to obtain the proper segregation you have to...

Hi, is there a specific reason why you are setting the specularity coefficient to 0.001? In Johnson and Jackson boundary conditions, a zero specularity coefficient corresponds to a perfectly...

It probably depends on the boundary conditions you are using. What kind of conditions did you specify? Could you provide some more information about the average particle concentration in your case...
