Dear Filippo
Thanks very much for your help
For momentum spatial discretization I use bounded central differencing as Fluent suggests. I assume unbounded second order discretization means second...

Thank you very much for your comment
It's true that in RANS we cannot compute energy spectra, however in DES we can do it as DES uses LES formulation in mean flow area and RANS formulation in...

Dear Mr. juliom and Mr. Filippo
Thank you very much for your reply.
Let me explain my case a bit more.
I am using Fluent and my inlet and outlet BCs are velocity-inlet and pressure-outlet....

Post Turbulence energy spectrum for a 3D curved pipe

Hi,
I need to make turbulence energy spectrum for a 3D curved pipe. I would like to see how LES is able to capture the turbulence flow details with my current mesh.
I followed many threads and...
