为研究电厂温排水对水域的温升影响,以巴基斯坦某火电厂下游温排水工程为例,应用水动力与输移联合数学模型建立了以非结构网格为基础的河道区域地形文件,对温排水运动的流场和温度场进行了二维数值模拟,获得了水面线、流速、温升影响范围、温升线沿岸扩散长度及包络面积,并与模型试验结果进行了对比验证。结果表明,该模型可正确地模拟温排水的流场并准确预测温排水对水域的影响。
In order to study the influence of thermal discharge of power plant on the temperature rise of water area, taking the downstream thermal drainage project of a thermal power plant in Pakistan as an example, a terrain file of river area based on unstructured grid was established by using the mathematical model of hydrodynamic and transport combined. The two-dimensional numerical simulation of the flow field and the temperature field of the drainage motion was conducted. The surface area, flow velocity, the influence range of the temperature rise, the diffusion length and the enveloping area along the temperature rise line were obtained and compared with the model test results. The results show that the model can accurately simulate the flow field of warm drainage and accurately predict the impact of warm drainage on the waters.
