{"cited_by_count":342500,"description":"This cluster of papers focuses on the phenomenon of cavitation in hydropower systems and turbines. It covers topics such as numerical simulation of turbulent cavitating flows, fluid-structure interaction analysis, pump operation as turbine, vortex dynamics, and the impact of cavitation on energy production. The papers also discuss cavitation prediction, large eddy simulation, and the influence of cavitation on hydropower efficiency.","display_name":"Cavitation Phenomena in Pumps","domain_id":"3","external_ids":{"openalex":"https://openalex.org/T11202","wikipedia":"https://en.wikipedia.org/wiki/Cavitation_in_hydraulic_machinery"},"field_id":"22","id":"T11202","keywords":[{"display_name":"cavitation","id":"cavitation","score":0.2862,"url":"https://openalex.org/keywords/cavitation"},{"display_name":"centrifugal pump","id":"centrifugal-pump","score":0.3057,"url":"https://openalex.org/keywords/centrifugal-pump"},{"display_name":"hydraulic turbines","id":"hydraulic-turbines","score":0.3805,"url":"https://openalex.org/keywords/hydraulic-turbines"},{"display_name":"cavitation erosion","id":"cavitation-erosion","score":0.395,"url":"https://openalex.org/keywords/cavitation-erosion"},{"display_name":"Francis turbine","id":"francis-turbine","score":0.7007,"url":"https://openalex.org/keywords/francis-turbine"},{"display_name":"cavitation number","id":"cavitation-number","score":0.7327,"url":"https://openalex.org/keywords/cavitation-number"},{"display_name":"pump efficiency","id":"pump-efficiency","score":0.2139,"url":"https://openalex.org/keywords/pump-efficiency"},{"display_name":"pump performance","id":"pump-performance","score":0.3319,"url":"https://openalex.org/keywords/pump-performance"},{"display_name":"turbine efficiency","id":"turbine-efficiency","score":0.2515,"url":"https://openalex.org/keywords/turbine-efficiency"},{"display_name":"cavitating flow","id":"cavitating-flow","score":0.7907,"url":"https://openalex.org/keywords/cavitating-flow"},{"display_name":"pump design","id":"pump-design","score":0.2309,"url":"https://openalex.org/keywords/pump-design"},{"display_name":"hydraulic machinery","id":"hydraulic-machinery","score":0.2153,"url":"https://openalex.org/keywords/hydraulic-machinery"},{"display_name":"pump-turbine","id":"pump-turbine","score":0.7752,"url":"https://openalex.org/keywords/pump-turbine"},{"display_name":"cavitation inception","id":"cavitation-inception","score":0.7222,"url":"https://openalex.org/keywords/cavitation-inception"},{"display_name":"hydrofoil","id":"hydrofoil","score":0.3473,"url":"https://openalex.org/keywords/hydrofoil"},{"display_name":"draft tube","id":"draft-tube","score":0.5383,"url":"https://openalex.org/keywords/draft-tube"},{"display_name":"Pelton turbine","id":"pelton-turbine","score":0.5578,"url":"https://openalex.org/keywords/pelton-turbine"},{"display_name":"low-head hydropower","id":"low-head-hydropower","score":0.6262,"url":"https://openalex.org/keywords/low-head-hydropower"},{"display_name":"micro-hydro power","id":"micro-hydropower","score":0.2773,"url":"https://openalex.org/keywords/micro-hydropower"},{"display_name":"turbine design","id":"turbine-design","score":0.2589,"url":"https://openalex.org/keywords/turbine-design"},{"display_name":"Kaplan turbine","id":"kaplan-turbine","score":0.5792,"url":"https://openalex.org/keywords/kaplan-turbine"},{"display_name":"guide vanes","id":"guide-vanes","score":0.3285,"url":"https://openalex.org/keywords/guide-vanes"},{"display_name":"impeller","id":"impeller","score":0.2162,"url":"https://openalex.org/keywords/impeller"},{"display_name":"turbine performance","id":"turbine-performance","score":0.2282,"url":"https://openalex.org/keywords/turbine-performance"},{"display_name":"cross-flow turbine","id":"cross-flow-turbine","score":0.3718,"url":"https://openalex.org/keywords/cross-flow-turbine"}],"legacy_keywords":["Cavitation","Hydropower","Turbulent Flow","Numerical Simulation","Cavitation Prediction","Fluid-Structure Interaction","Pump as Turbine","Vortex Dynamics","Large Eddy Simulation","Energy Production"],"openalex_id":"https://openalex.org/T11202","source_created_date":"2024-01-23T15:27:09","source_updated_date":"2026-10-17T03:02:00","subfield_id":"2211","url":"/topics/T11202","works_api_url":"https://api.openalex.org/works?filter=topics.id:T11202","works_count":61792,"label":"Cavitation Phenomena in Pumps","provider":"openalex","revision":"1382c53216cd4719","taxonomy_revision":"f050b5d4780b1289","title":"Cavitation Phenomena in Pumps","kind":"topic-directory","aeo_cohort":"topic-directory","catalogue_revision":"f050b5d4780b1289","numeric_address":"36240490726818549","address_version":"morton4x16-v1","coordinates":[3,22,2211,11202],"answer_status":"Directory metadata; local answer requires separate source review","truth_status":"Subject descriptor, not a factual answer or a demonstrated knowledge gap","reviewed_answer":null}
