Abstract

The lattice-Boltzmann method is employed to solve the none-Newtonian microporous flow field in the porescale under various rheological properties. The calculated local viscosity distribution in microporous structures corresponds with the non-Newtonian rheological properties. For the shear thinning fluid of power-law exponent n < 1, the fluid viscosity near the block surface is smaller. The flow rate through the porous structure is linear proportional to the applied pressure difference in logarithmic coordinates, keeping with the modified Blake-Kozeny equation.
