Green, J.R., Mishra, Rakesh, Charlton, M. and Owen, R. (2012) Validation of CFD predictions using process data obtained from flow through an industrial control valve. Journal of Physics: Conference Series, 364. 012074. ISSN 1742-6596

This study uses the experimental flow test data to validate CFD simulations for a complex control valve trim. In both the simulation and the experimental flow test the capacity of the trim (Cv) is calculated in order to test the ability of CFD software to provide a design tool for these trims. While CFD tests produced results for the capacity which were consistent across a series of five different simulations, it differed from the experimental flow data by nearly 25%. This indicates that CFD simulations need to be properly calibrated before being used in designing complex valve trims.
