I think the problem is related to the flow field somewhere between the inlet and the vortex finder. I can see that the turbulent viscosity ratio at this location is too high and after a couple of time steps solution diverges. nIt would be also helpful to mention that there is no issue when there are no particles. I could get a relatively good agreement between the calculated pressure drop and experimental values. However, when I introduce the particles everything falls apart.n
