i think that VOF is not appropiate for your problem, because the VOF model is appropriate for stratified or free-surface flows, however it is not appropriate for flows in which the phases mix or separate. moreover, The VOF formulation relies on the fact that two or more phases are not interpenetrating. instead you use the eulerian model in which you can model granular flow accurately. you can get all the literature you want from the fluent user's and tutorial guide.
