The transition for the large increase in lift due to the porous medium occurs at order one.
The theory has been applied to both impermeable and porous stationary and moving journal-bearing systems.
A similar relationship between average pressure gradient and velocity in macroscopic flow in porous media involves a proportionality parameter known as the permeability.
A three-phase ensemble-averaged model is developed for the flow of water and air through a deformable porous matrix.
The features of plasma dynamics caused by a discrete structure of porous media were taken into account.
In such systems the initial sample would be prepared and separated by standard electrophoretic or porous membrane techniques.
The dissolution and precipitation of crystals in porous media have been studied also in [7, 12] and [14, 17].
The porous medium is endowed with a heterogeneous microstructure.
