Flow and Transport in a Single Fracture Calculated from Laserscan or Tomography Data
Original language description
One of the challenges of modelling flow and transport phenomena in porous or fractured rock is capturing its heterogeneity, e.g. the microstructure geometry of pores and fractures, and obtaining the related parameters in the process equations. The presented work is composed of two case studies, based on experiments on splitted granite block with artificial fracture and on granite drill core with natural fracture (kept in a single piece), each processed in a different way into a numerical model. The presented approach is based on transforming and projecting the source CT values into a numerical 3D mesh of heterogeneous permeability for Darcy flow problem, so with use of the same equations and numerical methods as for other groundwater flow problems.
