Van der Walls particle interaction forces in two-fluid model

MFiX
#1

Hello, developers, is it possible to program the addition of particle interaction forces when simulating a fluidized bed with two-fluid model?

#2

Can you give some more detail about what type forces you want to add?

#3

Van der Waals force.

In TFM, you are looking at averaged quantities in a computational cell, not individual particle-particle interactions. You would need to do a literature search to see how to formulate Van der Waals forces in this context. Since MFiX is open-source, you would then have a chance to customize the code. This will require some time and effort.
