Hydraulic tortuosity in arbitrary porous media flow
Artur Duda, Zbigniew Koza, Maciej Matyka
Tortuosity () is a parameter describing an average elongation of fluid streamlines in a porous medium as compared to free flow. In this paper several methods of calculating this…

The maximal number of degenerate directions for non-piezoelectric media of trigonal symmetry
Artur Duda
We show that one can construct positively defined matrix of elastic constants representing medium of trigonal symmetry for which exactly 16 distinct degenerate directions exist.

Specific propagation directions for media of rhombic symmetry
Artur Duda
We reanalyze the problem of existence of longitudinal normals inside symmetry planes of piezoelectric crystals belonging to the symmetry class mm2. The equations determining compon…
