Default VOF xxxx drag force
Posts: n/a
Hi boys and girls!

Is vof model able to simulate correct drag force, anyway? I would doubt since there is no slip considered and velocity field is shared for both phases. In my case, I am simulating a free fall of droplet and it behaves like it was in vaccum (no terminal velocity)

any comments?

many thanks!! bohis
