Two phase flow - velocity problem

andyraq · July 15, 2016, 04:36

Hi.

I'm trying to simulate two phase flow (gas - solids) in unsteady state. After testing many k-e models i'm achieving the same problem - solids have their assumed velocity (12m/s) but after 3,5seconds of real time they pass a distance of 0,5 meters... whereas the first phase (air) with velocity 14m/s need only 0,5 second of real time to pass the whole model. Problem is represented in the picture below. Any ideas what could be the reason of this problem?
