Tortuosity Perturbations Induced by Defects in Porous Media
Résumé
In this chapter, we describe the effects of defects in a homogeneous saturated
porous medium. Defects are modelized by inclusions which disturb the motion of
the viscous fluid flowing in the pore space of the medium. The seepage rate of the
fluid in the host medium and in the inclusion is given by the Darcy’s law. Disturbances
thus produced modify the shape of the stream lines from which we establish
the tortuosity induced by the defects and its implications on the acoustic waves
propagation in saturated porous media.
