Linear and Nonlinear Waves in Porous Media Filled with Electrolyte
Linear and nonlinear acousto-electric waves in porous solids in the presence of an electric field are investigated. The pores are filled with an electro-conductive liquid. In (Shekoyan, 2011) nonlinear equations are derived from the variational principle that take into account the motions of solid and liquid phases and changes in porosity. In order to describe the seismo-electric effects, Maxwell equations are added to those equations (Shekoyan, 2011). This system is investigated using the method described in (Bagdoev, et al, 2009). The resulting self-consistent problem is solved while all the factors accompanying the wave are taken into account. Formulae for the wave's linear and nonlinear speeds and absorption coefficients are derived. Both 1-dimensional and 3-dimensional cases have been considered. Nonlinear evolutionary and Schrodinger equations are derived. Their solutions are obtained and investigated in detail. It is shown that there can be soliton-shaped waves in the medium.
