Abstract: | The flow of non-Newtonian fluids through two-dimensional porous media is analyzed at the pore scale using the smoothed particle
hydrodynamics (SPH) method. A fully explicit projection method is used to simulate incompressible flow. This study focuses
on a shear-thinning power-law model (n < 1), though the method is sufficiently general to include other stress-shear rate relationships. The capabilities of the
proposed method are demonstrated by analyzing a Poiseuille problem at low Reynolds numbers. Two test cases are also solved
to evaluate validity of Darcy’s law for power-law fluids and to investigate the effect of anisotropy at the pore scale. Results
show that the proposed algorithm can accurately simulate non-Newtonian fluid flows in porous media. |
