Local analysis of flow conditions within a geometrically complex control valve trim using CFD

Computational Fluid Dynamics software has been used to simulate the flow conditions within a geometrically complex control valve trim. The results of this simulation are then analysed to find velocity and static pressure profiles at critical points within the trim to investigate the trim's ability to limit erosion caused by high flow velocities and cavitation. The CFD analysis carried out showed that trim offers favourable features against these causes of erosion for this trim design.
