Gas Decompression

Question asked by Bryan Penn on Mar 5, 2018

How would I go about modeling a pressurized tank venting air to atmosphere over time? If I set my boundary conditions to a given pressure, flow simulation will assume that pressure is constant. I would like to set a starting pressure and model the tank depressurizing to get a plot of pressure drop over time.

 

Edit: I would really like to know how much time it will take for pressure within the tank to equalize with environmental pressure.
