瓜渚湖水流控导工程水动力数值模拟分析
Hydrodynamic Influence Analysis of Control Project in Guazhu Lake Based on Mathematical Simulation
摘要
Abstract
In order to study the project measures for enhancing the hydrodynamic of Guazhu Lake,the selected range included diversion works and lake surroundings. A two-dimensional mathematical model numerical simulation method was used to calculate the hydrodynamic factors,such as flow velocity and water level,the hydrodynamic characteristics of the lake waters was analyzed and three low velocity zones existing in the lake was disclosed. On the basis of above analysis of the existing low velocity properties,three water streamlining control and diversion works were designed by the theory of flow separation and vortex and flow control. The results of hydrodynamic calculation indicate that the water flow into these low velocity zones and velocity increases by the action of laid streamline guiding and control buildings,and there is no obvious vortex at the tail of flow around works,the flow resistance and head loss are also decreased.关键词
