Combining a linearized … WebOct 29, 2001 · In this paper we present an acoustic propagation model that approximates a porous medium as a fluid with a bulk modulus and effective density derived from Biot theory. Within the framework of Biot theory it is assumed here that the porous medium has low values of frame bulk and shear moduli relative to the other moduli of the medium and …
WebIn Biot's theory (Biot 1956a, b), pore fluids are forced to participate in the solid's motion due to inertia and viscosity. The Biot mechanism is described through macroscopic rock properties and based on the macroscopic flow. ... and the isotropic description of the solid/fluid coupling effects developed by Biot . Furthermore, Yang & Zhang ... WebThe Biot-Savart integral can now be recast and evaluated as follows.
