Study of the influence of surfactants and surface treatments on the minimum wetting rate of falling films of aqueous LiBr and Carrol solutions
(Elsevier, 2022-09)
Artículo
Acceso restringido por política de la editorialThe wettability is one of the critical properties of the falling film type absorber, limiting the wetting area in the absorber, hence the total mass transfer performance. To achieve low values of wetting rate in the ... -
