Effet d'un traitement de surface léger sur la performance de transfert de chaleur et de masse d'un absorbeur à film tombant de H2O/LiBr.

Résumé

The objectives of this study were to develop a new method of wettability measurement, to investigate the effect of micro-scale surface treatment on the wettability in a LiBr/H2O falling film absorber and to apply the wettability to numerical analysis of heat and mass transfer in a LiBr/H2O falling film absorber. Three absorber tubes with micro-scale roughness were tested. The wettability of the structured surface was higher than that of the bare tube. Variations in wettability (according to several parameters) were studied.
