摘要
本文依据水流运动的基本理论,并考虑风对水体的剪切作用,应用改进的移步ADI法,建立了风作用下流场的数值模似系统,其结果与连续四年的实测资料验证相吻合。计算预报了于桥水库三个典型水文年定常风不同风速、风向的流场,并由计算机绘制出彩色流场图。文中还针对计算应用成果进行了分析。
Yuqiao Reservoir is an important regulating-impounding reservoir of the diversion project to channel the Luanhe water to the city of Tianjing. An analysis of the flow field affected by the wind is the main way of studying the transportation-diffusion of pollutants and eutrophication of Yuqiao Reservoir. Based on the governing equations of fluid movement, and water surface shear stress under the action of the wind, a numerical simulation system of flow field has been developed by means of moving Alternating Directional Implicit Method. The simulation results are in very good agreement with the original data measured in the last 4 years. In addition > the flow field under the effects at stationary and unstationary situations of wind on 3 typical hydrographic years is predicated, a color picture of flow field given out, and its application discussed.
