Reverse modeling method for lateral water inlet structure of sediment-carrying water source pump station and its application in flow field analysis
摘要
Abstract
Bottom siltation with complex geometric shapes has a special impact on the water-sediment flow fields within the lateral intake structure of pumping stations.In order to accurately construct a re-fined three-dimensional computational domain model of the lateral water inlet structure under siltation,restore the geometric feature information of the silted structure as much as possible,and further explore the water-sediment transport characteristics and flow state changes of the intake structure under sedi-mentation,a reverse modeling method based on reverse engineering technology for lateral intake struc-tures with complex boundary conditions was preposed,a complete three-dimensional computational do-main model that can be used for fluid dynamics calculations was constructed,and the hydraulic charac-teristics of the intake structure under siltation state were analyzed.The results of the study show that the maximum modeling deviation of the three-dimensional reverse modeling method proposed in this study is only 1.598 1 mm,which can accurately reflect the actual geometric boundaries and sedimentation morphology of the water intake structure,and the numerical simulation results are consistent with on-site tests.Although sedimentation improves the local flow field structure,it causes a loss in the overall hydraulic performance of the structure.This method can provide new ideas for geometric modeling and optimization of sediment structures with complex contour boundaries.关键词
