Dear MFIX Contributors,
I would like to know whether the PIC in the current mfix-19.2 version can be applied to polydispersity calculation and whether the collision force model in it includes viscous collision?
Thank you!
Currently the only way to incorporate polydisperse particles into MFIX-PIC is by prescribing multiple solid phases of different diameter.
Also note that there is no collision force model in the current MFIX-PIC. MFIX-PIC is controlled through the examination of local solids stress, which affects the momentum equation through a source term. The inclusion of general polydispersity and a collision sub-model are under development.
