Hi,
I'm intending simulate a multiphase flow in a bioreactor. The initial proposal is apply a one way or two way coupling model to perform the particles behavior and residence time. Is it possible apply CFDEM - LIGGGHTS to acess this kind of flow? Does anyone have any suggestions?
Thank's in advance.

Hi! could you specify your
Hi!
could you specify your bioreactor in some more detail?
Cheers,

Hi Chris! Thank you for your
Hi Chris!
Thank you for your prompt reply.
Our initial studies are based in cilyndrical bioreactor geometry, as can be observed in the file attached above.The tank is composed by a tangential inlet and an internal outlet. Initially, we are intending to simulate a flow with homogeneous particles (with same diameter and density) using one or two-way coupling and a Lagrangian model to perform the particles behavior and the respective residence time. The other fluid is water. Simplifications in the flow simulations are a requirement in our study, because these simulations will be used as a solver in an optimization routine.
Best regards.

Hi Jonas, possible
Hi Jonas,
possible limitations to using a CFD-DEM coupling method are:
-nr of particles is too big (simulation time)
-size of the particles is bigger then grid size (convergence)
If above criteria are fine - it should be feasible.
Cheers,
Chris
