某拦河闸式渠首闸门调度及运行方式的数值模拟研究

Numerical Simulation of A Sluice Gate Intake Gate Scheduling and Operating Mode

采用数值模拟的方法,对新疆某渠首工程的闸门调度及运行方式进行了三维数值模拟,并对不同工况下典型断面的流量、水位及流速进行分析。研究表明数值模拟与物理试验得出的结果吻合情况较好,不同工况下的渠首运行方式均可达到较优的泄洪、引水效果,三维数值模拟的方法能够弥补物理试验费时费力,并且对流场内部特性难以掌握的缺点,可用于类似渠首工程运行方式的数值模拟研究,并为实际工程的运行控制提供参考。

The numerical simulation method was used to simulate the 3-D flow field of the gate scheduling and operation of a headwork in Xinjiang .And then the typical cross-section flow ,water level and flow rate in different conditions were analyzed .The results suggest that the numerical simulation results are in good agreement with those of the physical test , all the headworks operating modes under different conditions can reach better effects of flood discharge and water diversion in the simulation .Furthermore ,3-D numerical simulation method can make up for the shortcomings of the physical tests , which are time and energy consuming as well as the inadequate grasp of the internal characteristics of the flow field . Therefore it can be used in the numerical simulation study of similar headwork operation modes and provide some refer-ences for the operational control of practical engineering projects .
