数理与机理双驱的数字孪生冰期输水系统研发
Development of dual-driven mathematical and mechanistic digital twin system for ice-period water transfer
摘要
Abstract
To accelerate the development of a digital twin model for water network engineering,this study integrated prototype observation,mechanistic analysis,and numerical simulation.It employed water temperature data-driven models as core engines,including thermodynamic-hydrodynamic and ice-water coupling models for high-precision simulation of ice-water dynamics.By comprehensively analyzing the spatiotemporal distribution characteristics of water temperature and ice conditions in the Middle Route of the South-to-North Water Diversion Project over the past decade,a digital twin application system for ice-period water transfer has been developed.This system supported real-time monitoring and early warning of ice and water conditions,intelligent forecasting of water temperature and ice dynamics,risk assessment of ice-jam flooding,multi-scenario simulation of ice formation and melting processes,and winter ice-flood prevention scheduling,which has been successfully applied to ensure safe water transfer and assess ice-flood risks during the 2023-2024 winter season.This research provides robust technical support for disaster prevention,risk reduction,and the intelligent development of the Middle Route of the South-to-North Water Diversion Project.关键词
