Dear all:
Could the cut-cell of mfix achieve annular flow by adopting PIC method? Like this:

And if so, how do I do that?

It could. You would need two cylinders for the external and internal walls. One thing to remember is that you need to have sufficient computational cells between the two walls to correctly capture gradients. I suggest no fewer than five uncut cells.

@jmusser Thank you very much for your help, I will try to do it as you suggest.

Hi Yubinjia,

How did you build the annular cylindrical shape fluidized bed as you showed in the picture? Could you share your code with me? Thanks a lot!
