Hi friends
I want to simulate two phase mixture model consist of water and 5% of Fe3O4 in fluent.
I appreciate you for your replays.
1-How can i define Stokes drag coefficient in mixture Model (Cd=24/Re) ? is Stokes drag coefficient equal to Morsi-Alexander drag coefficient?
2-for simulation nanofluid do I have to use granular in secondary phase ? why or why not ?
3-for calculating the secondary phase (nano particle) viscosity What should I define viscosity value 0 or infinity ? or other thing ?

Thank you.
