新疆博斯腾湖二维水动力数学模型研究

Study on Bositeng Lake by 2D Hydrodynamic Mathematical Model

风场是影响湖泊水动力的重要因素,它可以改变水体运动速度和方向,影响各种物质在湖泊内的输移扩散。通过分析博斯腾湖大湖区风场,准确估算出风力、风向变化情况,构建了博斯腾湖平面二维水动力模型。应用计算模型对博斯腾湖水动力进行模拟预测,分析不同风向、风速对湖泊流场结构的影响,为进一步研究博斯腾湖水动力和污染物输移扩散提供理论依据。

the wind field is the main factor impacting the hydrodynamic force in lake. It can change the speed and direction of the water body motion as well as ＇affect the transport and dissipation of subjects in lake. Through the analysis of the wind fields in the large lake area of the Bositeng Lake, variations of wind power and direction are precisely estimated as well as the plan 2D hydrodynamic force model of the Bositeng Lake is established. By application of the model, the hydrodynamic force of the Bositeng Lake is simulated and predicted, impacts on the structure of the lake flow fields by different wind direction and speed is analyzed. These provide the further study of the hydrodynamic force and transport ＆ dissipation of pollutant in the Bositeng Lake with theoretical basis.
