Porous media equations

WebIn this paper, we consider a class of convection-diffusion equations with memory effects. These equations arise as a result of homogenization or upscaling of linear transport equations in heterogeneous media and play an important role in many applications. First, we present a dememorization technique for these equations.

GOVERNING LAWS AND EQUATIONS The basic law for governing the fluid flow through porous media is the Darcy’s law that was given by the Henry Darcy in 1856 by the experiments on vertical water filtration through the sand beds. The thorough study related to diffusion was performed by R. W Zimmerman in 2002 [14].
