温差异重流散热研讨

STUDY ON HEAT RADIATING BY STRATIFIED FLOW OF DIFFERENCE IN TEMPERATURE

以模型试验为基础，以色水为示踪剂模拟热水，研讨以齿状长堰过水方式将集中排放在水下的高温热水，转换成过水宽度为千米长的表层温度最高的温差异重流，以借助水面热交换解决冷却池散热问题，为充分利用水资源，扩大火电厂装机容量提供了可靠的试验研究成果．文中还给出了温差异重流的温度场模型和任一过水断面流速分布式．对从事有关研究的工程技术人员有一定的借鉴作用．

A new method of heat radiating by heat exchange in water surface on cooling pool in power plant is studied. Take model test as the foundation and coloured water as tracer to imitate heat water, which are concentrated to displace under the water by a long weir in teeth. It is changed into stratified flow of difference in temperature with passage width in thousand metres and very high surface temperature. This new method supplies reliable test result to full use the water resources and enlarge the installed capacity in power plant. The model of temperature field in stratified flow of difference in temperture and the formula on velocity distribution in any passage section are also introduced. That is certain of an experience function to the enginees on concerned research.
