本文描述了一个实验程序，该程序旨在量化喷雾水蒸发成温暖干燥气流的速率，并应用于拟议的充气织物管道冷却塔。织物风管冷却塔的充气特性促进了快速展开，并在炎热、干旱的环境中为人类提供了低能耗的冷却。该试验装置测量了与加热气流平行流动的分散水滴的传质系数。数据简化方法采用了强迫对流传热和蒸发传质之间的类比。对于原型充气织物蒸发冷却塔中使用的特定雾化喷嘴，实验表明，平均试验段舍伍德数是水-空气质量流量比的幂律函数，其指数等于0。 70.同样，由此产生的舍伍德数与喷射水注入的下游距离成反比。引用:佛罗里达州奥兰多2020年冬季会议技术论文

This paper describes an experimental program that wasdesigned to quantify the rate of spray water evaporation intoa warm, dry airstream with application to a proposed inflatablefabric duct cooling tower. The inflatable nature of thefabric duct cooling tower promotes rapid deployment, andprovides low energy cooling for human comfort in hot, aridenvironments. The test apparatus measured the mass transfercoefficient for dispersed water droplets flowing parallel to aheated air stream. The data reduction approach employed theanalogy between forced convection heat transfer and evaporationmass transfer. For a specific misting nozzle used in aprototype inflatable fabric evaporative cooling tower, theexperiments demonstrated that the average test section Sherwoodnumber was a power-law function of the water-to-airmass flow rate ratio, with the exponent equal to 0.70. Likewisethe resulting Sherwood number was inversely proportional tothe downstream distance from the spray water injection.
