Tortuosity is one of the most elusive parameters of porous media. The fundamental question
is whether it may be computed from the geometry only or the transport equations must be …

The article is related to a computational method of obtaining the geometric tortuosity in
granular beds, ie polydisperse beds consisting of spherical or quasi-spherical particles …

Since it was first theorized more than half-century ago, nanotechnology has proven to be the
perfect boost for existing technologies and the oil industry has made use of this avant-garde …

In the paper, functions describing different porosity-tortuosity relations were collected, and
then the tortuosity values were calculated for a one granular bed consisting of spherical …

Natural and hydraulic fractures existence and state differs on a reservoir-by-reservoir or
even on a well-by-well basis leading to the necessity of exploring the flow regimes variations …

We report new measurements of the concentration‐dependent longitudinal dispersion
coefficient of aqueous urea and ethyl acetate solutions in a porous medium at a wide range …

In this paper, a methodology of calculating the tortuosity in three-dimensional granular beds
saved in a form of binary geometry with the application of the A-Star Algorithm and the Path …

Chapter Highlights This short Chapter is devoted to the wonderful world of tortuous
pathways inside the pore space of rocks, available for fluids, electric current, heat, sound …

Since it was theorized more than 50 years ago, nanotechnology has become the perfect
boost for existing old technologies. The unique properties exhibited by materials at these …
