Wetting dynamics of nanoliter water droplets in nanoporous media.
TL;DR: In this article, a new theoretical model was developed to characterize the corresponding wetting dynamics of nanoliter water droplets in nanoporous media, and it was demonstrated that even for an intrinsically hydrophobic nanoporous substrate, spontaneous imbibition of a noliter droplet can occur if capillary condensation had occurred internally already.

Capillary pressure and liquid wicking in three-dimensional nonwoven materials
Ningtao Mao,Stephen J. Russell +1 more
TL;DR: In this article, a model is established for predicting the directional capillary pressure in three-dimensional nonwoven materials by adapting the hydraulic radius mechanism and drag force theory, and equations to predict the velocity of liquid wicking in a one-dimensional wicking strip test for non-wovens having a 3D fiber orientation distribution are given.

Spontaneous imbibition of liquids in glass-fiber wicks. Part I: Usefulness of a sharp-front approach
TL;DR: In this paper, a single-phase Darcy's law was used to model the spontaneous imbibition of a liquid into glass-fiber wicks, where the authors assumed a sharp flow-front marked by full saturation behind the front occurring in a transversely-isotropic porous medium.
Journal ArticleDOI
Tuning capillary penetration in porous media: Combining geometrical and evaporation effects
TL;DR: In this article, a theoretical model of capillary penetration combining evaporation effects in two-dimensional homogeneous porous media of varying cross-section is developed and further examined by numerical simulations.

Advancing Contact Angles of Newtonian Fluids During “High” Velocity, Transient, Capillary-Driven Flow in a Parallel Plate Geometry
TL;DR: In this article, the authors measured contact angles in the order of 70° to 80° for Newtonian fluids at relatively high capillary numbers using a system of parallel glass plates, and fitted the transient height attained by the fluids between the plates to an averaged-flow Navier−Stokes model in order to indirectly estimate the value of the dynamic advancing angle.
