A study of the coupled heat and mass transfer during absorption process in a spiral tubular absorber

Design enhancement of an adiabatic LiBr-H2O absorber through a droplet flow optimization

“…Similar results were obtained later by Ben Hafsia et al [78], although droplet formation and fall were not considered separately; nevertheless, they concluded that between 74% and 77% of the total mass absorption occurred during the combined droplet formation and fall regime.…”

Improved of effective wetting area and film thickness on a concentric helical bank of a generator for an absorption heat transformer

“…Hafsia et al [7] recommend also that the flow rates employed in the practice should be sufficiently low in order to maintain a continuous flow by drop fall between the tubes, to facilitate absorption and increase energy in the system. However, mixing the falling film by increasing the liquid loading is sometimes done.…”

“…Detailed studies on the falling film in a spiral tubular absorber were made by Hafsia et al [7]. They developed also a model that describes the absorption kinetics in three different flow regimes: falling film regime, droplet formation and droplet fall regimes, following the model described by Kirby and Perez-Blanco [8].…”
