Analysis and Research on the Properties of Horizontal Jet of Temperature Difference in Wide and Shallow River

布置在宽浅河道上．采用直流供水的火电厂冷却循环水系统的排水口温差射流，对冷却循环水系统的取水条件和环境水温、河道通航条件等均有明显的影响．本文利用实际工程模型的试验资料，对受河道水流作用的排水口温差射流的特性进行系统的分析．归纳出射流轨迹、射流纵横剖面流速和温升分布规律．

In a wide and shallow river, it is very cvident to note that the distributions of water temperature, the condition of inland navigation, and the working order of intake are influ- enced by the horizontal jet of temperature difference from the outlet of cooling water circula- tion of the power plant. The cxperimental data of the model of some cooling water circulation were used for making systematic analysis on the properties of horizontal jet of temperature difference which suffers the action of the river current. As a result of the analysis, the jet tra- jectory, the laws of distribution of longitudinal and traverse velocities, and the temperature rise of the jet are obtained.
