Simulating a half filled eppendorf tube in a centrifuge

Please login with a confirmed email address before reporting spam

Dear all,

We try to model the flows in an eppendorf tube while it's rotating in a centrifuge (positioned under an angle).

We where succesfull in simulating a fully filled tube using the rotating machinary module in 3D. Now we want to expand the simulations to also include half filled tubes (water at the bottom and air at the top). Unfortunatly we find that the rotating machinary module only offers mixture models for multiphase flow.

Has anybody a good suggestion on which modules or combination of modules is best used to tackle this kind of problem ?

With Kind Regards Sander Stroobants and colleagues.
