Pore-Scale Flow
This non-conventional model of porous media flow utilizes Navier-Stokes equations in the interstices of a porous media. The model comes from the pore-scale flow experiments conducted by Arturo Keller, Maria Auset, and Sanya Sirivithayapakorn of the University of California, Santa Barbara. The geometry used in the model was produced by scanning electron microscope images.In this example, we take one of the 2D micromedia images of Keller, Auset, and Sirivithayapakorn and solve for velocities and pressures of pore fluids using the Navier-Stokes equations for Cartesian coordinates. Boundary integration is used to quantitatively evaluate fluxes.
