In CFX, the free surface model with surface tensio force used interface compression. How is this different from interface reconstruction like PLIC algorithm. Can know the pros and cons of both.
What software uses interface reconstruction and compression.

why is interface drag not modelled in homogeneous free surface model.

CFX uses a compressive scheme for the volume fraction. It does not have a reconstruct scheme like Fluent does.

There is no interface drag in homogenous flow - both phases by definition are moving with no relative slip because they are homogeneous! That is why there is no interface drag model.

Can you please explain me how compressive scheme for volume fraction works in CFX. Are there any related equations.

I am not sure if it is in the documentation. If you cnanot find it then ask ANSYS support. I think the ANSYS CFX multiphase training course also covers it.

Ok, I got the details of the model. Thanks.
