How to compute forces on a moving fluid-fluid interface?

Hi all,
I’m using Comsol Multiphysics 3.5a to model the formation of an oil droplet from a single pore. The droplet is carried away by a continuous phase(water) which flows parallel to the opening of the pore. I’m using Level Set method in order to track the moving oil-water interface. How can I do to compute the total viscous forces exerted by water on the droplet surface? Shall I use Matlab Interface? And in this case, which commands are useful to carry out this operation?
Many thanks
Giuliana

Hi
Tricky question you have there, as with the Level Set method you do not have a geometrical surface defined to integrate over as for the other models methods.
Basically, I would look into how to define the surface to integrate the stress over it, or use the droplet volume and try out a "work" approach to get hold of the boundary presure.
Pls keep us informed I find your question is very interesting, the solution will be to
Good luck
