Hi everyone,

I have some doubts about how to modify continuity condition on internal boundaries and I would ask for some help.
I want to solve hydrodynamics on a unit cell of the Taylor flow (known also as slug flow or bubble-train flow) in a circular millichannel. This unit cell is composed by a bubble and two liquid half-slugs. I consider that bubble have a fixed shape and remains immobile.
So, what I want is to solve Navier-Stokes equations into the two subdomains (bubble and liquid) considering the gas-liquid interface as an internal boundary but establishing a "No penetration" condition as done by the "slip boundary condition".

Thanks in advance,
Freddy
