Journal ArticleDOI
Tortuosity-porosity relation in porous media flow
TL;DR: It is demonstrated that the finite-size, slow relaxation and discretization errors, which were ignored in previous studies, may cause significant underestimation of tortuosity.
Journal ArticleDOI
Hydraulic tortuosity in arbitrary porous media flow.
TL;DR: An alternative method is proposed, which enables one to calculate T directly from the fluid velocity field, without the need of determining streamlines, which greatly simplifies determination of tortuosity in complex geometries, including those found in experiments or three-dimensional computer models.
Journal ArticleDOI
Intensive and extensive nitrogen loss from intertidal permeable sediments of the Wadden Sea
Hang Gao,Maciej Matyka,Bo Liu,Arzhang Khalili,Joel E. Kostka,Gavin Collins,Stefan Jansen,Moritz Holtappels,Marlene Mark Jensen,Thomas H. Badewien,Melanie Beck,Maik Grunwald,Dirk de Beer,Gaute Lavik,Marcel M. M. Kuypers +14 more
TL;DR: In this paper, Nitrogen (N) loss rates were determined in permeable sediments of the Wadden Sea using a combination of stable N isotope incubation experiments and model simulation approaches during three seasons.
Proceedings ArticleDOI
How to calculate tortuosity easily
Maciej Matyka,Zbigniew Koza +1 more
TL;DR: Tortuosity is defined either as an average elongation of fluid paths or as a retardation factor that measures the resistance of a porous medium to the flow as discussed by the authors, and is one of the key parameters describing the geometry and transport properties of porous media.
