Hi guys

I wanna impose fully developed flow at the inlet of a duct. I do not have much time so what will be best option to do that. All kind of ideas are welcome. Thanks in advance for your help.

Hi!

Take a look at tutorial n°9

No unfortunately that wont help because that tutorial is for circular pipes. I have a rectangular duct. Any idea how to write an expression for a duct of 2*0.5*0.5? Inlet velocity is 2 m s^-1. Thank you

make a simulation with a long tube! after that, take the profile of velocity at oultlet and use as the inlet for the nest simulation! how about it?

Good idea Rogerio but unfortunately I do not have time to run a simulation in very long. If I use periodic boundaries that too would give me fully developed flow. Only problem is that I am being able to use periodic boundaries for compressible flow. Any idea how to sort this issue. Thank you

if u want, i can make this type of simulation! My MSN is rogeriobrito2007@hotmail.com

Hi Rogerio

I have added you but you are not online right now. I hope to get in touch with you soon.
