采用数值模拟的方法分析由含湿多孔陶瓷管组成的被动蒸发冷却墙体(PECWs)的换热性能。研究不同排列方式对空气温度及水蒸气质量分数的影响,研究得出:在含湿多孔陶瓷管处于叉排布置情况下,流经其表面的空气温度变化和相对湿度变化较大,而且蒸发冷却效果更佳。
The heat transfer performance of passive evaporative cooling wall (PECWs) composed of porous ceramic tubes containing moisture is analyzed by numerical simulation. The effects of different arrangement on air temperature and water vapor mass fraction were studied. The results showed that the temperature and relative humidity of the air flowing through the surface of the porous ceramic tube fluctuated greatly when the porous ceramic tube was arranged in a fork arrangement, and the evaporative cooling Better effect.
