Reflection of attenuated waves at the surface of a fractured porous solid saturated with two immiscible viscous fluids

摘要: The mathematical model for wave motion in a fractured porous solid is solved the propagation of harmonic plane along general direction 3-D space. solution obtained form Christoffel equations, which are further to define complex velocities and polarisations five attenuated wavesin medium. Four these waves longitudinal one transverse wave. For any waves, inhomogeneous considered with specification slowness vector involving finite non-dimensional inhomogeneity parameter. phase attenuation coefficients calculated each A numerical example studies analyse effect frequency, saturating pore-fluid, volume fraction fractures parameter on velocity attenuation. phenomenon reflection studied calculate partitionof wave-induced energy incident at boundary solid. fractures, pore-fluid partition example.
