Hi guys,
I have a simulation of multiphase flow (Water flow in a conduct with air injection by a hydrofoil place in the middle) and I use the grace drag model. I inject 1mm bubbles diameter. I notice that the volume fraction correction exponent have influence on my solution (Crash or not ). I read the help menu in Ansys for this correction exponent but not give enough info...For small bubble use a value of -1, and larger bubble a value of 4...I did a little search on the net for more info but i didn't have succes, has anyone have some infos, links to give me about that? Thank you Math |

I would like to raise this question again.
Mathieu, did you (or someone else) find anything on this topic? I am desperately looking for it. |
