摘要:本文主要根据冷却水物理模型试验关键相似条件,对于上海CJ电厂一、二、三期取排水工程冷却水物理模型进行了设计 。详细介绍了对典型水文条件下的温差水流实验,测得了表层温度分布场、 垂线温升分布以及取水口取水温升。结果表明, 该模型较好地复演了原体水流流态, 为减轻温排水相互影响程度及对环境影响的评价提供了科学的依据, 并为各期循环水取排水工程安全、可靠、经济的运行提供了保证。

Experimental investigation on cooling water of
Abstract:According to the key similarity criteria of physical model for cooling water ,This paper introduces the design for the cooling water model of water supply and drainage project in first and second stage.For the temperature difference test under the different hydrology , the surface temperature field and vertical temperature distribution and excess intake temperature were measured.The result shows hat the model not only duplicate prototype flow state well , but also offers scientific evidence to EIA and relief the extent of mutual influence of heated discharge , and provides secure for the safety of cy2 cling water project s of every stage , t rustiness of and economy of .
Keywords: thermal flow outflowing shanghai CJ power plant surface temperature field inflow temperature rise physical model
