We study fluid flow and conduction in a two-dimensional model of a fracture with rough, self-affine internal surfaces. The model consists of two parallel flat plates on which two rough, self-affine surfaces, characterized by a roughness exponent H, are superimposed. The methods that we use for computing the effective flow and transport properties of the fracture include the lattice Boltzmann method for computing the flow properties, a random walk method for determining the effective...[Show more]
