摘要

本文研究了工业自然通风冷却塔(NDCT)内的水和空气分布不均匀性。绘制了NDCT中水流和气流分布的统计直方图，建立了显著程度的水流和气流不均匀性，并引入了无因次水流和气流分布的一般判据。通过对流量分布规律的分析，发现自然通风冷却塔内的水气流量统计数据均服从正态分布规律。得到了水浓度和风速的无因次分布函数。对不均匀流动对火电厂燃料消耗的影响进行了技术经济计算。在冷却塔的设计和运行中，了解水和空气的浓度分布规律是进行准确计算所必需的。

The water and air distribution law analysis in natural draft cooling towers

This work deals with the study of water and air distribution irregularity in an industrial natural draft cooling tower (NDCT). Statistical histograms of water and air flow distribution in the NDCT are made, a significant degree of water and air irregularity has been established and a general criterion for the dimensionless water and air distribution has been introduced. We have analyzed the flows’ distribution law and have found that the statistical data of water and air flow in natural draft cooling towers adhere to the normal distribution law. The distribution functions of the dimensionless of water concentration and air velocity are obtained. A technical and economic calculation of the irregularity flows influence on the thermal power plant fuel consumption has been carried out. The knowledge about the law of the water and air concentration distribution is necessary for more accurate calculations in the cooling towers design and operation.
