Understanding Flow in Deformable Porous Media

This course covers the comprehensive understanding of flow through deformable porous media. It focuses on the varying porosity, effective stress, and the behavior of deformable porous media like quicksand or easily crushed soil. The course explains the concept of compressive strain and its relation to changes in porosity. It also discusses the conservation of mass of the solid constituent in a porous medium and its effect on fluid flow. For instance, the course uses examples like the compression of a gel structure or a sponge to explain these concepts. Furthermore, the course delves into the concept of flow through a deformable porous medium, the occurrence of deformation due to compressive stress, and fluid flow due to gradient in pore pressure. It introduces the concept of composite velocity, Darcy's law in the context of deformable porous media, and the relationship between excess stress, pressure, and deformation gradient.
