Hi,

I am wondering if this type of simulation is possible:

There is a glass tube, filled with liquid up to 60%. This tube has a cap and the air portion inside the tube is under vacuum (relative to room pressure). There is a small channel inside the cap. This channel is closed initially. At time = 0+, the channel is open to room pressure.

I would like to simulation air rushing into the tube and how it disturbs the liquid inside.

Is this possible? Any suggestion?

Pei
