Hello everyone,

It is m first post in those forums and I just recently started using CFX (and doing any fluid dynamics) - please forgive me if I am asking about silly things.

What I would like to do is to estimate friction factor for an inner annulus wall with roughness elements of known height and spacing. I managed to build the geometry and set the physics - it is a one phase turbulent flow - since I did have some experimental data. I would be very grateful for any help with how use CFX for estimation of friction factor for the rough inner wall surface.

Thanks in advance for your help,
George
