Hi,

I'm planning to simulate a flow in a tube with heat transfer. Which solver is the most appropriated?

Thanks in advance,

Marco.

Hi,

must be turbulent.

Thanks,

Marco.

It depends what you want to solve:

- If it's just the forced convection in the tube, I would recommend you the solver buoyantSimpleFoam.
- If you also want to simulate the conduction in the tube layer, better use a multi-regions solver as chtMultiRegionSimpleFoam.

Though, it might be different given your case: Is it subsonic? Does radiation matter? etc...

Please, give more details of it for further help.

PS: and have a look at the wiki and the forum search function

Have a nice day

Hi Sixwp,

Thank you for the reply. Actually I'm planning to simulate just subsonic forced convection. No radiation. Then buoyantSimpleFoam is the best option, ok?

Many thanks,

Marco.

Default The flow should be internal.

Hi Sam,

The flow should be internal forced convection in a tube. No buoyancy is needed.

Regards,

Marco.

Hi

Buoyancy will have a negligible effect in most cases unless you have two phase flow.

If you want T and U to be uncoupled (i.e. no buoyancy effect) you can easily modify say the simpleFoam solver to include the energy equation.
