在系统研究湖泊、水库各项水动力影响因素的基础上,建立了湖流模拟系统,其中包括水流叠加波浪后波流的共同作用、波浪剩余动量流、风作用剪应力、风吹流以及悬移质扩散分布等。数值模拟中还采用了几种处理技术,并对ADI法进行了双向双步扫描改进。在引滦入津输水工程中的于桥水库湖流计算预报的应用表明,计算结果与现场实测吻合良好,具有计算精度高、收敛快、稳定性好、通用性强等优点。
Based on the systematical study of hydrodynamic factors of lakes and reservoirs, a simulation system of lakes and streams was established, including the interaction of post-wave and post-wave currents, wave residual momentum flow, wind-induced shear stress, Diffusion and other distribution. In the numerical simulation, several processing techniques are also used, and the ADI method is improved in two-way and two-step scanning. The application of calculation and forecast of Yuqiao water transfer project in Luan River to Tianjin water transfer project shows that the calculated results are in good agreement with the field measurements and has the advantages of high calculation accuracy, fast convergence, good stability and versatility.
