Good morning,
I need help. I have a totally developed flow in a square duct with cyclic conditions. I have made some works with bar velocity (with commented code) and now i want to do a work with a fixed gradient pressure in order to have a fixed Reynolds number of friction(with the code in fvOptions). How can i do? I have thought to fix the pressure gradient with the code of momentum source in fvoption. But i can't how can i do. Could you give me some help, please? This is my fvOptions: /*momentumSource { type meanVelocityForce; selectionMode all; fields (U); Ubar (1 0 0); }*/ accelerationSource { type accelerationSource; active on; selectionMode all; U U; velocity one; value (10 0 0); } |
