The effect of surface tension is not included in the drag!

The drag force is a result of the friction at an interface separating two phases. If the two phases are solid and air, we do not have...

I asked the same question in the ANSYS Student Community, someone from ANSYS stuff answered it.

The answer does make sense for me. If you looked at a momentum equation for the Eulerian model, you...

Post How does ANSYS FLUENT model the surface tension in the Eulerian (multi-fluid) model?

I am using ANSYS FLUENT to model a two-phase flow of liquid and gas where the surface tension force is included.
In the theory of the VOF model, the surface tension force is added to the momentum...
