On modelling the parallel diffusion flow in deforming porous media

Cimrman, Robert; Rohan, Eduard - In: Mathematics and Computers in Simulation (MATCOM) 76 (2007) 1, pp. 34-43

We present a macroscopic model of the fluid diffusion in deformable porous media, motivated by diffusion-deformation phenomena influencing the heart muscle blood perfusion, or the mechanical properties of kidneys. The problems are described by the displacement field and by several fluid pressure...

The surface diffusion coefficient for an arbitrarily curved fluid–fluid interface. (II). Coefficient for plane-parallel diffusion

M.C. Sagis, Leonard - In: Physica A: Statistical Mechanics and its Applications 291 (2001) 1, pp. 103-112

In this paper we developed an expression for the coefficient for plane-parallel diffusion for an arbitrarily curved … and calculates the plane-parallel diffusion coefficient as a function of the perpendicular distance to the dividing …
