Hello,
I try to heat the air in a cavity. Initially, the air is at 300K. It is heated up to around 419K. Why the pressure changes only 19Pa? In my opinion, refer to ideal gas law, the pressure should increase at least 0.4atm. From what I've set: Air-Ideal gas, Boundary condition-no gravity, 0Pa as reference pressure, and solve in transient Please help me. How can I set the Fluent to get reasonable pressure? Thank you very much. Noppawit |
