This paper illustrates how to set up and solve a two-dimensional flow problem having dimensions of 640 x 320 micro-meter using the Navier-Stokes equations with the help of COMSOL Multiphysics solver.
The principle of our pore-scale modeling approach is composed of two steps. The first step involves the detailed identification and specification of the porous medium morphology, this step was done previously using the scanning electron microscope (SEM). Once the pore morphology is obtained, the second step is initiated using COMSOL software.
The constitutive relation between permeability and properties of a realistic porous medium has also been determined and compared numerically through Darcy’s law depending on the x-velocity field and pressure distributions that had been obtained.
