This included a detailed CFD analysis of fixed cone valves and butterfly valves, which a renowned manufacturer specially customised. ### Cone valves and their importance for energy dissipation Fixed cone valves, which contribute to efficient energy dissipation due to their free outlet, are crucial for regulating the flow, emergency drawdown processes in dams or as a turbine bypass. ### CFD analysis with high-precision mesh structures For the analysis, mainly structured meshes with hexahedron elements were generated, in particular to accurately map the complex geometries around the flap plates of the butterfly valves. This detailed refinement enabled us to precisely resolve all relevant 3D structures for the numerical simulation. ![](https://www.jabergundpartner.com/fileadmin/_processed_/a/e/csm_uebersicht_ventile_ENG_86a157a04b.webp)Overview of the arrangement of the fixed cone valves and butterfly valves as well as the network structures of the CFD analysis Our results helped the operator optimise the hydraulic design of the system and prove its emergency emptying capability. ![](https://www.jabergundpartner.com/fileadmin/_processed_/d/7/csm_cfd_fixed_cone_valve_6586572c20.webp)The coloured streamlines represent the flow velocity of the water, whereas the streamlines drawn in white represent the aeration from the ventilation pipes. ### Additional insights gained from the analysis The results of our analysis also provided further valuable insights into the mechanical loads on the valves and the necessary ventilation requirements, which represented considerable added value over and above the original scope of the project.
