摘要
辽宁省铁甲水库入库口水动力场比较复杂,为准确了解其特征,文章进行了辽宁省铁甲水库入库口水动力场特征数值模拟研究,通过α坐标和正交曲线坐标转换建立数值模拟模型,并对模型水温的表面及底部边界条件、自由表面边界条件以及侧向开边界条件进行限制,根据模拟区域实际情况对模型参数进行设置,最后通过该区域历史数据导入对流速进行反演,模拟结果表明辽宁省铁甲水库入库口区域以往复流形式为主,并且离岸距离越远,往复流特征越明显,水流运动比较强,最大流速可达到3.45m/s,平均流速为2.34m/s。
Inlet hydrodynamic field of Tiejia Reservoir in Liaoning Province is more complex.Numerical simulation study of inlet hydrodynamic field characteristics of Tiejia Reservoir in Liaoning Province is studied in the paper in order to accurately understand the characteristics.The numerical simulation model is established through conversion ofαcoordinate and orthogonal curvilinear coordinate.The model water temperature surface,bottom boundary condition,free surface boundary condition and lateral boundary conditions are limited.The model parameters are set according to the actual circumstance of simulation area.The flow velocity is inversed finally through the regional historical data import.The simulation results show that the inlet area of Tiejia Reservoir of Liaoning Province is mainly based on the complex flow form.The offshore distance is farther,the reciprocating flow is more obvious,and the water flow motion is stronger.The maximum flow velocity can reach 3.45m/s,and the average flow velocity is 2.34m/s.
