Fully Developed boundary condition in Fluent

shinjanghosh · May 2, 2019, 15:30

Hi

I am trying to do a pin fin array heat transfer simulation in Fluent and I need to cut down my domain in order to save time. The Fully developed condition should help me do that. However, I looked online for a fully developed mass flow inlet and couldn't find one anywhere. I would greatly appreciate any inputs on how to make a fully developed internal flow with a fixed mass flow inlet.

Thanks,
Shinjan

You need to use the streamwise periodic boundary condition. It needs some text commands

define/boundary-condition/make-periodic blah blah blah
