Hello mam/sir,
I hope you remember my two-phase flow case through the rectangular channel using COMSOL Pde's tool. Here I am writing my simulation condition and which kind of problem i am facing.
I have done the simulation for single-phase flow through the rectangular channel, which is the based on Poisson equation. No-slip boundary condition used at the top and bottom walls. The periodic boundary condition has taken at the left and right side walls. I did not get any trouble for this case. I have discussed my problem below
I want to do a two-phase flow case for a rectangular channel. In this case, I have an interface. At this interface, the boundary conditions are tangential stress are equal and velocities. So that I am unable to set, these two boundary conditions at the interface. According to your today's lecture, we can use weak constraints to define boundary conditions. I tried but still unable to get the solution.
It's a standard problem in two-phase flow. I have attached one control file and one jpeg file. Please go through the jpeg file. I hope you better understand my question. I am unable to replicate for two-phase flow problem. Please go through the all attached files and fix my problem.
Thank You and waiting for your reply.
