摘要
介绍FLOW-3D数值模拟和物理模型试验在海口市龙塘大坝枢纽改造工程水流条件研究的应用,通过各工况的数值模拟与物理模型试验,对水闸水流流态、流速和沿程水面线等水力特性进行计算与观测。经对比分析,各工况下FLOW-3D数值模拟和物理模型试验所得的流态、水面线、流速变化及分布规律基本一致,为研究泄水建筑物布置及体型设计的可行性及合理性,泄水建筑物设计及运行管理提供了科学依据。
This paper introduces the application of FLOW-3D numerical simulation and physical model tests in studying the water flow conditions of the Longtang Dam in Haikou City.By numerical simulations and physical model tests for each operating conditions,the hydraulic characteristics of the sluice,including flow patterns,velocities,and water surface profiles,are calculated and observed.The comparative analysis reveals that the flow patterns,water surface profiles,velocity variations,and distribution laws obtained from both FLOW-3D numerical simulation and physical model tests are basically consistent under various operating conditions.This provides a scientific basis for studying the feasibility and rationality of layout and shape design for water release structures,as well as for their design and operational management.
