There is oil in the pipeline, and water is used to replace it. Which model is suitable?
Euler or vof?

You need to provide a schematic of your setup so we can suggest you the best approach. But two incompressible, immiscible fluids - VOF should work fine if the conditions are favorable - like a simple stratified flow morphology (an interface that's simple enough to be tracked, no complex regions in the pipeline geometry etc).

I agree with Rahul, If you are interested in the interface between the 2 fluids you may have to use the volume of fluid model (VOF).

I can't see the picture you sent. Can I send it again? Thank you

I don't know if this divergence has anything to do with the number of meshes in my model.
My model is 20m long, 10m wide, the thickness of the thin plate channel is 10mm, and the radius of the hemispherical cavity is 3m.
Mesh painted with icem. Structure grid is about 80,000. It is then converted to an unstructured grid. The quality of the grid can also be.
