Abstract: We investigate the dissolution of artificial fractures withthree-dimensional, pore-scale numerical simulations. The fluid velocity in thefracture space was determined from a lattice-Boltzmann method, and a stochasticsolver was used for the transport of dissolved species. Numerical simulationswere used to study conditions under which long conduits wormholes form in aninitially rough but spatially homogeneous fracture. The effects of flow rate,mineral dissolution rate and geometrical properties of the fracture wereinvestigated, and the optimal conditions for wormhole formation determined.
