Simulation of fracture rock solute transport with multidimensional dual-porosity model

Original language description

We propose a combined model, where the entities of fractured rock structure are represented by means of corresponding 1-D, 2-D (fractures) or 3-D (rock continuum) elements, each including dualporosity (mobile and immobile zone). The transport is governedby the advection?diffusion equation in each of the 1-D, 2-D and 3-D domains, coupled with first-order mobile-immobile exchange and solved using a finite-volume numerical scheme. We solve a test problem of contaminant breakthrough through a single fracture surrounded by rock. Then we compare representations by a 1-D coupled mobile and immobile zone geometrically identical to fracture, the 1-D mobile zone as fracture and the 2-D mobile zone as the rock. The results confirm similarity in macroscopic behaviour of both models such that the difference between the results is less then 5% of the ratio of fracture and rock conductivity higher than 100.

Model transportu látky v prostřední rozpukané horniny pomocí tzv. multidimenzionálního přístupu kombinovaného s modelem dvojí porozity

Czech description

Je definován model transportu látky v prostřední rozpukané horniny pomocí tzv. multidimenzionálního přístupu kombinovaného s modelem dvojí porozity (mobilní a imobilní zóna) pro každou dimenzi. Je řešena modelová úloha transportu na lineární puklině obklopené vrstvou horninové matrice a na profilech a průnikových křivkách porovnány výsledky pro různé varianty modelu.
