摘　　要：采用基于能量方程的条带分析方法,对矩形河槽流速进行了模拟,在对模拟结果进行验证之后,将模型应用在拟建柏叶口水库三维流场研究中。通过适体坐标变换生成水库曲线型计算网格,将生成的曲线型网格细化、分层、分条带,最后用基于能量的方程进行一维、二维和三维的流场计算。整个模拟过程易于编程实现,并可通过设置网格的疏密程度,有效控制流场的计算精度。该方法可推广应用于其他水库的流场计算、水库三维温度场和污染物浓度计算。The stripebelt analysis method based on energy equation is adopted to simulate the flow speed of rectangular river channel.After the simulated results are tested,the model is used to simulate the 3-D flow field of Baiyekou reservoir to be built.The reservoir curved type computation grid is generated via the changes in a boundary-fitted coordinate.The generated curved-type grid can be fined,stratified and striped.Finally,the equation based on energy is used to carry out 1-D,2-D and 3-D flow field calculation.The calculated flow field accuracy can be effectively controlled via the setting-up of the looseness and compactness degrees of grids.The whole simulation process is easily realized via programming and the accuracy can be effectively controlled.Accordingly,this method can be extended in the application of flow field calculation of other reservoirs,reservoir 3-D temperature field and pollutant concentration calculations.
