Double emulsion simulation

I have done my single emulsion simulation now I am trying the double emulsion simulation in COMSOL Multiphysics I am not getting the double emulsion droplets microfluidics.

Hello Kavyashri,

Consider uploading you .mph file. Without one, it'd be difficult for Discussion Forum readers to give you much insight into why your model behaves the way it does.

Best,

Jeff

Double emulsions are harder to get than single ones because you’re simulating three fluids and two interfaces, so small setup issues can break it. If you’re not seeing the inner droplet form, it’s usually due to incorrect flow rate ratios, surface tension between phases, or initial phase setup. Also make sure your mesh is fine enough and your multiphase model (Level Set/Phase Field) is tuned properly.
