Physical and numerical experiments of flow and transport in heterogeneous fractured media : single fracture flow at high Reynolds numbers, and reactive particle transport

Physical and numerical experiments of flow and transport in heterogeneous fractured media : single fracture flow at high Reynolds numbers, and reactive particle transport

The first part of the thesis is focusing on an experimental study of single phase flow processes in a single granite fracture. In order to obtain the aperture field, two different measurement methods were developed and evaluated. The effect of heterogeneities of the aperture field was shown by a vis...
