摘　　要：在简化的三维水槽模型基础上,选取k-ε紊流模型,采用数值模拟的方法分析了沿海电厂不同取排水布置下温排水的热扩散规律,及各自布置下的环境影响大小,研究了取水温升值随取排水管道间距及半径变化下的情况。结果表明,在本文工况下,差位式取排水方式较重叠式更适宜、经济。Based on the simplified model of three-dimensional tank,the k-ε turbulence model is selected in this paper and numerical simulation is performed to analyze the heat diffusion law under different water drainage arrangements of the coastal power plants and the environmental impact of each arrangement,and the variation of the intake water temperature rise with the spacing and radius of intake（drainage） pipes is studied.The results show that under the assumed working condition in this paper,the differential water intake（drainage） method is more suitable and economical than the eclipsed one.
