Natural Convection (Operating Pressure condition)
I am simulating a closed vesel natural convection problem in Fluent. My task is to check the heat transfer coffecient variation with the change in initial pressure.
There are no inlet or outlet boundary conditions and the only condition impose on the system is isothermal condition on the wall of the vessel and heat generation in the fluid.
I have used Boussinesq approximation for density specification and I need to do transient state analysis.
My problem is when I plot the pressure variation along X dimension of vessel it show almost zero value of pressure (dynamic pressure) in the whole domain even if I set operating pressure as high as 5 bar. I assume I am missing somewhere in specifying the operating pressure condition. Kindly let me know if the experimental pressure condition was 5 bar how should I specify the operating pressure to reproduce the experimental results.
Please help me in the same....
Thanks in advance

Let me first ask you: why are you interested in the dynamic pressure?. Shouldn't you look for the static value?
