摘　　要：介绍了水动力模型的基本控制方程、数值模拟方法、边界条件以及水动力模拟在应用中的基本过程,采用水动力模拟对曹妃甸蓄水池进行了水质提升研究。通过对曹妃甸蓄水池进出水口更改前后进行水动力模拟,可知将出水口改至进水口对角,可以促进水体在蓄水池内的流动,减小部分水域的换水周期。通过对曹妃甸蓄水池进水污染物进行水动力模拟,可得污染物在进入蓄水池后的转移分布情况,为进一步的工程实施提供了有效的理论支撑。Basic control equation,numerical simulation method,boundary conditions and basic using process of hydrodynamic model were introduced.Hydrodynamic model was used to improve the water quality in Caofeidian reservoir.Hydrodynamic simulation of water inlet and outlet of Caofeidian reservoir was carried out,and hydrodynamic simulation was carried out again after the water outlet was adjusted to the opposite angle of water inlet.Changing outlet could promoted the flow of water in reservoir and reduced water retention time in some water areas.Through hydrodynamic simulation of inlet pollutants of Caofeidian reservoir,distribution of inlet pollutants after entering reservoir are obtained.All these provide effective theoretical support for further implementation of project.
