one/two way coupling of DPM
hi, everybody! I have a question of the coupling mechanism of two phase flow in Fluent using DPM model--- Stochastic tracking. Where can I adjust the coupling between phases? I mean one-way coupling and two-way coupling. Or for Stochastic tracking, is the coupling mechanism only of one way coupling? In my understanding, for stochastic tracking, the influence of fluid phase on praticle is realized by the second item u'i of instantaneous fluid velocity ui=ui+u'i. Is that right? For the two-way coupling , how can praticle affect the fluid phase? How can I realize it in FLUENT?

Re: one/two way coupling of DPM
Hi, I think it is in 'the interaction with cont. phase'

define - models - discrete phase first line : interaction....

I think it is not possible to do Two way coupling when you are using RANS (that's what I heard, you'll have to look it up)

Hi,Ebrahim. Thank you for your reply. I feel much clear now.:)

No problem :) try to see my question ;-)
