Effective Darcy-scale contact angles in porous media imbibing solutions of various surface tensions

Creator:

Weisbrod, Noam, McGinnis, Thomas, Rockhold, Mark L., Niemet, Michael R., and Selker, John S.

Abstract:

Surface tensions of high-salinity solutions are significantly different from those of pure water. Our objective was to develop and test a methodology to determine whether these surface tension effects predictably alter imbibition into dry and moist porous media. Static and dynamic experiments were performed using four grades of quartz sand...

Water vapor transport in the vicinity of imbibing saline plumes: Homogeneous and layered unsaturated porous media

Creator:

Weisbrod, Noam, Niemet, Michael R., McGinnis, Thomas, and Selker, John S.

Abstract:

Water vapor transport in the vicinity of imbibing saline solutions was investigated in two-dimensional (2-D) chambers using a light transmission technique. Concentrated NaNO3 solutions (brines) were applied as point sources to the surface of homogenous packs of prewetted silica sand for four different sand grades. The same solutions were applied...
