摘要/Abstract

摘要： 水面综合散热系数、糙率、涡粘性系数和热扩散系数是温排水数值模拟过程中的重要参数,各参数的正确选择与计算直接影响到温排水数值模拟成果的准确性。以沿海某核电厂为例,分析各参数的取值对1 ℃最大温升面积模拟结果的影响,并对各参数的灵敏度进行分析,以期对后续沿海核电工程的温排水数值模拟工作提供参考。

Abstract: Water surface evaporation coefficient,roughness, eddy viscosity and thermal diffusion coefficient are important parameters in the process of numerical simulation of warm water drainage. Correct selection and calculation of them may affect the accuracy of simulation results directly. Taking a coastal nuclear power plant as an example, the effect of parameter selection on simulation results of the maximum temperature rise area of 1 ℃was analyzed. The sensitivity of each parameter is also analyzed. It expects to provide reference for the numerical simulation of warm water drainage in future coastal nuclear power projects.

Key words: Warm water drainage, Numerical simulation, Sensitivity
