Numerical study of Bingham flow in macroscopic two dimensional heterogeneous porous media
Résumé
h i g h l i g h t s • We solve the flow of yield stress fluid at large scale using a Lattice Boltzmann method. • On a large scale, in the presence of heterogeneities, yield stress fluids exhibit fractal flow structures. • These fractal properties are characterized by different scaling exponents that are independent of the amplitude of the heterogeneities.
