Continuum-fracture model for transport processes: Error analysis
Original language description
Deep subsurface deposits in plutonic rock represent one of possible solutions for final storage of nuclear waste. The primary reason is small hydraulic permeability of the bulk rock and thus slow migration of a possible leakage due to ground water flow. On the other hand, granitoid formations contain fractures that may form a network of preferential paths with low volumetric water flow rate but with high velocity. The preferential paths pose a risk of fast transport of small amount of contaminant but in potentially dangerous concentrations. The large scale effect of the small scale fractures is challenging for numerical simulations since direct discretization requires highly refined computational mesh. This contribution deals with one possible approach based on modelling fractures as lower dimensional objects and coupling them with surrounding continuum.
