Mach number in a Nozzle
 

Hi all...
I'm trying on learning Fluent to analysis fluids in a nozzle, and I don't know the way to show the Mach Number. If anybody know it, please help me
Thanks a lot...

As soon as you have defined your working fluid as compressible one (ideal gas) Ma-Number gets available in the Contours/Velocity category

cheers

Thanks coglione. I got Much Number from your help. Do you have any experience about ejector. I'm researching in Ejector steam which using the water as the working fluid with primary pressure is 1bar. Can you give me any advise. once again thank you so much...
