I would like to know if it is possible to fix a flow rate with a cyclic BC.
My goal is to have a fully developed flow on all the pipe (= without an entrance region).
I use OpenFoam 2.2.2

Thank you

Hi Marc-Aurele,

you can go to through this document from page 11 to 13. The idea is to add an average pressure drop as a source term in your momentum equation. The pressure you solve is then the deviation to the average pressure. Hence, you can consider cyclic condition to the "pressure" field.

cyclic boundry condition, flow rate, fully developed flow
