I also need to simulate a similar case in a 3-phase model, which is liquid-liquid-gas system. My domain is a rectangular tank where it has two immiscible liquids (oil and water). A gas bubble is in the bottom of the tank moving upwards. How can I define the surface of the gas bubble as a no-slip condition? That means the gas bubble can be properly treated as a solid sphere. After the gas bubble surrounded by water goes through the liquid-liquid interface in the tank, the sphere will be surrounded by the oil as similar as the situation described above. How can I modify the physical condition for the liquid-liquid interface on the gas bubble? The boundary condition between liquid-liquid interface when the gas bubble moves upwards needs to be no-slip as well.
Any suggestions and advice are appreciable!! Expecting your reply!!

May i kindly ask you to upload your .sim file (one that contains bubbles model) somewhere and share?
I've got a bit similar case - jet injected into the volume.
