Tank Pressure Release

Hello all,


It's more theoretical question now, but I am trying to start CFD in near future.


Let's assume tha there i a pressure vessel (let's say 2l - paintball btttle) withe Oxygen inside under pressure of 10 MPa (@ certain temperature). I will need to simulate how the internal pressure inside a tank will change via time for certain valve  throtlling.  I need to capture also the temperature change of the fluid as well. Is there easy way to do it?


How to start with such task? I am pretty new in hydrodynamics / CFD so all publications are most welcome aprat of the practical tips.


Many thanks ! Smiley Happy
