【摘要】：从气象要素和水体表观特性要素两大方面着眼,利用风洞开展正交实验,考察7种不同因素对蓄水屋面被动蒸发效果的影响。研究发现,太阳辐射对蒸发的影响最显著,其次是水深、水面污染程度和水面浅色漂浮物覆盖率,而环境空气温度、相对湿度和风速的影响较弱。高太阳辐射照度、中等水深、干净水面、一定覆盖率的水面浅色漂浮物、高温、低湿、中等风速最有利于促进蒸发。
[Abstract]:From two aspects of meteorological elements and apparent characteristics of water body, the effects of seven different factors on passive evaporation of water storage roof are investigated by using wind tunnel orthogonal experiment. The results show that solar radiation has the most significant effect on evaporation. The second is the depth of water, the degree of water pollution and the coverage of light colored floating objects on the surface, but the influence of ambient air temperature, relative humidity and wind speed is weak. High solar irradiance, moderate water depth, clean water surface, light color floating objects with certain coverage, High temperature, low humidity, moderate wind speed is most conducive to promote evaporation.
