Default Fluid-2 domain interface
Posts: n/a

I am solving for laminar flow past a fluid sphere (a CCl4 dropping in a infinte medium of glycerol-hadamard theory) inside a cylindrical tube.

If i use fluid-2 domain interface for the interface, then the outside fluid will simply enter inside the sphere (this is because in CFX fluid-2 domain interface means a mesh connection only). So i am getting straight fluid-2 lines rather than curved around the sphere.

Moreover if i use wall boundary condition for the interface, the outside fluid will take a curved path around the sphere(rightly so), but continuity of momentum sources wont be applied by CFX.

So velocity and pressure profiles inside the drop cant be captured.

how to do this in CFX.
