研究了横流状态下空气与降液膜之间的传热传质问题。研究了cu超细颗粒的加入对强化传热传质过程的影响。采用参数化方法研究了相关控制参数对除湿和冷却过程及其后续优化的影响。研究发现，空气雷诺数越低，除湿降温效果越好。增加通道的高度和长度，减少通道的宽度，增强除湿和冷却过程。研究还发现，cu体积分数的增加增加了除湿和冷却能力，并产生了更稳定的cu溶液。(C) 2003 Elsevier Ltd.版权所有。
Heat and mass transfer between air and falling solution film in a cross flow configuration is investigated. Effects of addition of Cu-ultrafine particles in enhancing heat and mass transfer process are also examined. A parametric study is employed to investigate the effects of pertinent controlling parameters on dehumidification and cooling processes and their subsequent optimization. It is found that low air Reynolds number enhances the dehumidification and cooling processes. An increase in the height and length of the channel and a decrease in the channel width enhance dehumidification and cooling processes. It is also found that an increase in the Cu-volume fraction increases dehumidification and cooling capabilities and produces more stable Cu-solutions. (C) 2003 Elsevier Ltd. All rights reserved.
