Dynamics of non-Newtonian fluid interfaces in a porous medium: Compressible fluids (Q1119082)

This paper deals with the illustration of rheological effects of non- Newtonian displacing and displaced fluids on the dynamics of a moving interface in a porous medium. Both fluids are considered to be compressible. Specifically, the rheological effects are shown and discussed on the interface position and on its velocity in terms of rheological parameters of power-law fluids. The approximate analytical solutions are obtained for the boundary and initial conditions of practical interest, from which an optimal policy of injection can be found to control the dynamics of a moving interface in oil displacement mechanism.
