COMSOL two phase flow with slip boundary condition

Click For Summary
SUMMARY

The discussion centers on modeling two-phase flow in COMSOL Multiphysics, specifically addressing the implementation of a slip boundary condition at the interface between two fluids with different properties. Users are advised to explore the Level-set method or phase function for this purpose. A reference to a relevant academic paper is provided, along with a suggestion to utilize the COMSOL community forum for quicker responses.

Hey all,

I am try to model a problem in which one fluid (of known properties) sits on top of another fluid (with different properties) and there is an imposed slip boundary condition at the interface.

I'm wondering if COMSOL has a Slip boundary condition that can be readily used or if I'll have to use the equations to impose one. I have read online that the Level-set/phase function might need to be employed but I'm not completely sure how to use it.

Any insight or comments would be appreciated!

Pleasemesh,
Have you seen this paper: http://www.comsol.com/academic/papers/628/ it may help you.
You can also try asking on the http://www.comsol.com/community where you may get a faster answer.
