rhoCentralFoam
1 Attachment(s)
Hi everybody!
I'm trying to simulate a subsonic flow in a nozzle. I've tried to do this with rhoCentralFoam but the simulation didn't give good results. I don't know if it comes from my BC's or if rhoCentralFoam can't deal with subsonic flow. I've attached my 0 folder to show you my BC's. Thank you for your help. |
Hello,
what do you mean when you say "no good results"? Donīt they reach a steady state or anything else? regards treima |
After one iteration, I've got a Mach number of 0.43 but I know after analytical calculations that my maximum Mach number has to be more or less 0.1 at steady state.
Thank you! |
Your case looks like its adapted from a 2D case. If this is what you want, then the frontAndBack boundaries should be of tpe "empty" for all your variables; in some of them they are "empty", in some they are "zeroGradient".

For a Mach number about 0.1, is it really necessary to use a compressible solver?
