Abstract [en]

The sorption process plays a significant role in the retardation of solute transport through the fractures. In this paper, based on the measured data of rock surfaces by laser scanning, a 2D geometry model of a representative single rock fracture was built and its roughness was statistically characterized, and a Finite Volume Method (FVM) code was developed and applied to solve the NS equation and transport equation for numerical modelling the process of fluid flow and solute transport. Two groups of simulation were then calculated: with and without the consideration of the sorption process, with different average flow velocities. The effects of sorption on the solute transport process were then analyzed, discussed and followed by concluding remarks on the sorption impact on the understanding of mass transport process in fractured rock masses.
