Hi all
I simulated fully developed flow using openfoam. I need to calculate pressure drop. The problem is that the pressure boundary condition at the inlet and outlet are cyclic and therefore pressures are the same at this boundaries. Is there any way to calculate actual pressure and subsequently pressure drop?


an early reply would be highly appreciated

I should mention that i added a source term in the momentum equation via fvoption.

so you impose the pressure gradient (drop)....
