Hello, I would like to create a situation where the cooler works in a perfectly sealed compartment. |

As stated in the FDS Technical Reference Guide, FDS uses the Ideal Gas Law as the Equation of State: PV = n R T If you have a sealed compartment then V (volume) is constant, the gas constant R is constant, and n (moles of gas) is constant. What happens to P (pressure) if T (temperature) decreases? When looking at pressure outputs make sure you understand what quantity you are looking at. Some pressure outputs are total pressure (i.e. 101 kPa at t=0) and some outputs are the perturbation pressure (0 kPa at t=0). |
