CFDEM vs DPMFoam

I am wondering if anyone compares the implementation of gas-solids coupling in these two codes. I got quite different results for the same problem. Attached is a snapshot comparing the two simulations. Any comments will be appreciated. Thanks.

Hi

Dear litingwen,
I am very interested in this topic. I have used CFDEM for a period of time. In CFDEM, we only take the interaction between filtered fluid velocity and particles into account, the turbulence in a sub-grid is filtered and neglected, so I want to use DPMFoam in OpenFOAM. I study gas-solid hydrodynamics in fluidized beds, so I’d like to discuss with you.

Interesting

I cannot tell from the comparison, but the CFDEM coupling itself has seen a ton of validation and verification ( see for example http://www.sciencedirect.com/science/article/pii/S0045793015000675 and etc) whereas I have not seen the DPM model from OpenFOAM used in a thorough manner as of now, thus I would be more inclined to have better faith in the former...

Cheers,
Bruno
