Computational fluid dynamics (CFD) has been used for some time successfully for fluid flow studies through valves. Using CFD is a fast and beneficial tool, which can also be applied to bigger valve sizes for analyzing purposes.
If you will participate in the Conference, welcome to the Control Valve session (Room 1, at 11:00) on November 29th to learn more, I'll give a presentation on CFD in control valve cavitation modelling!

P.S. Later on Tuesday my colleague Ville Kähkönen will talk on Correct valve selection for ESD in the Safety / SIS session (Room 1, at 16:20).
