研究了倾斜平行流和逆流流条件下空气与干燥膜之间的传热传质。提出了两种不同的结构，并进行了参数化分析。考察了倾角对空气除湿和冷却过程的影响，并根据相关参数研究了液体干燥剂的再生。在干燥剂膜中加入cu超细颗粒，研究空气与干燥剂膜之间的传热传质增强情况。相关参数包括空气和干燥剂的雷诺数、空气和液体干燥剂的进口条件、cu超细颗粒的体积分数和热分散。结果表明，倾角对提高除湿、冷却和再生过程具有重要作用。(C) 2003 Elsevier Ltd.版权所有。
Heat and mass transfer between air and falling desiccant film is investigated for inclined parallel and counter flow configurations. Two different configurations are proposed and parametrically analyzed. Effect of inclination angle is examined to study enhancements in dehumidification and cooling processes of the air and regeneration of liquid desiccant in terms of pertinent parameters. Cu-ultrafine particles are also added to the desiccant film to investigate the enhancement in heat and mass transfer between the air and the desiccant film. The pertinent parameters are air and desiccant Reynolds numbers, inlet conditions for both air and liquid desiccant, Cu-ultrafine particles volume fraction, and thermal dispersion. It is shown that inclination angle plays a significant role in enhancing the dehumidification, cooling, and regeneration processes. (C) 2003 Elsevier Ltd. All rights reserved.
