Abstract

A study of the tracer diffusion and hydrodynamic dispersion in two-dimensional fractures was performed. The fractures possessed self-affine roughness and analysis was made using lattice-Boltzmann approach using boundary conditions for tracer particles. The fractal geometry of the fracture surfaces reduced the diffusive transport for different fracture apertures. The correction for the diffusive transport was calculated in terms of tortuosity in the limit of small aperture fluctuations. Dispersion was studied when the two fracture surfaces were displaced normally to the mean fracture plane.
