In this paper, the desalination performance of a plant variant with the same size as the Manzanares pilot model was numerically investigated. A three-dimensional compressible flow and heat transfer model has been developed, describing the air cooling process along the chimney and the associated condensation. In this plant variant, instead of installing the turbine, water droplets were sprayed for evaporation at the bottom of the chimney, and thus airflow was subjected to humidification. Results show that with increased mass fraction of water in the air, the influence of the microclimate on the local environment will also increase. The evaporation of the droplets improves the relative humidity of the air within the chimney, and the condensation level can thus be greatly reduced. Moreover, the freshwater output increases with increasing amount of water sprayed, which is beneficial for the improvement of the desalination efficiency of the system.

在本文中，对与Manzanares中试模型大小相同的植物变体的脱盐性能进行了数值研究。已经开发了三维可压缩流动和传热模型，描述了沿烟囱的空气冷却过程以及相关的冷凝。在该工厂变型中，代替安装涡轮机，而是在烟囱底部喷洒水滴以进行蒸发，从而对气流进行加湿。结果表明，随着空气中水质量分数的增加，小气候对当地环境的影响也将增加。液滴的蒸发改善了烟囱中空气的相对湿度，因此可以大大降低冷凝水平。而且，
