Eulerian Granular flow:receive reverse flow and solution isn't converge
1 Attachment(s)
Hi all friends
I want to modeling steady state two-phase flow of liquid - solid using Eulerian-Granular approach in Fluent but when I do it,I receive Reverse flow in pressure inlet and outlet message (my BCs are pressure inlet&outlet) and solution isn't converge. A two-dimensional (2-D) axisymmetric model was created and meshed with Gambit as shown in attach picture. multiphase particulate (volume fraction= 0.2) fluid was pumped into the main model inlet (with pressure inlet=13.8Mpa), and mingled with multiphase particulate (volume fraction = 0.8) fluid was pushed from the bottom inlet(pressure inlet=13.8Mpa) then flow to outlet(pressure outlet=10.3Mpa). I've tried both steady and unsteady state with different URF but solution isn't converge. particle diameter:45e-6 m particle density:2350 kg/m3 fluid density:1000 kg/m3 solid fluid interaction:syamlal o'brien Assuming a wall boundary instead of the porous medium and drill string/pipe is wall BC in domain. please guide me Regards |
steady-state granular flow
Hi,
did you manage to solve the problem because I have the same problem. thanks in advance! Best! Quote:
