Résumé

Heat and mass transfer between air and a falling desiccant film were investigated for inclined parallel and counter flow configurations. Two different configurations were proposed and parametrically analysed. The effect of the inclination angle was 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 were 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 air and liquid desiccant, Cu-ultrafine particles volume fraction, and thermal dispersion. It was shown that the inclination angle plays a significant role in enhancing the dehumidification, cooling, and regeneration processes.
