Dear Community, Do any one have any idea of finding out the initial gauge pressure while simulating a supersonic flow is there any formula or something from which I could find that thing out.
Please help
Advance thanks

Hello,
If you know the stagnation pressure at the inlet of your domain you can use the isentropic relations to calculate the static pressure. This is the supersonic gauge pressure in fluent provided you set the operating conditions to 0Pa

Cheers

Please provide more details of the information of the problem you have got. Only then possible equations or ideas will come to people here

Cheers

I am simulating a sonic flow in a nozzle with air ideal gas.
