On compressible and piezo-viscous flow in thin porous media
In this paper, we study flow through thin porous media as in, e.g. seals or fractures. It is often useful to know the permeability of such systems. In the context of incompressible and iso-viscous fluids, the permeability is the constant of proportionality relating the total flow through the media to the pressure drop. In this work, we show that it is also relevant to define a constant permeabi...
متن کاملViscous Potential Flow Analysis of Electrohydrodynamic Capillary Instability through Porous Media
The effect of porous medium on the capillary instability of a cylindrical interface in the presence of axial electric field has been investigated using viscous potential flow theory. In viscous potential flow, the viscous term in Navier-Stokes equation vanishes as vorticity is zero but viscosity is not zero. Viscosity enters through normal stress balance in the viscous potential flow theory and...
متن کاملPostbreakthrough behavior in flow through porous media.
We numerically simulate the traveling time of a tracer in convective flow between two points (injection and extraction) separated by a distance r in a model of porous media, d=2 percolation. We calculate and analyze the traveling time probability density function for two values of the fraction of connecting bonds p: the homogeneous case p=1 and the inhomogeneous critical threshold case p=p(c). ...
متن کاملFlow control of fluids through porous media
This paper discusses flow control of fluids through porous media, specifically related to its application in petroleum science. The flow of fluids is described by the Boussinesq equation with mixed boundary conditions; a Neumann boundary condition describes no flow at the outer boundary of the porous media and a nonlinear boundary condition describes the interaction between the porous media and...
متن کاملSedimentation and Flow Through Porous Media : SimulatingDynamically
We describe a method to address eeciently problems of two-phase ow in the regime of low but non-zero particle Reynolds number and negligible Brownian motion. One of the phases is an incompressible continuous uid and the other a discrete particulate phase which we simulate by following the motion of single particles. Interactions between the phases are taken into account using locally deened dra...
