Abstract: This study investigates the dynamics of granular flows in geotechnical centrifuge models, focusing on the effects of centrifugal and Coriolis accelerations. While conventional laboratory-scale investigations often rely on Froude scaling, geotechnical centrifuge modelling offers a… read more here.

DOI: 10.1103/physrevfluids.6.124302
Abstract: We study the direction-dependent drag acting on a cylindrical solid intruder with length L and diameterD as it moves in water-saturated granular beds at constant depth. Polysterene and hydrogel grains with diameter d are used… read more here.

DOI: 10.3997/1873-0604.2017055
Abstract: The complex conductivity method has been frequently used in solving hydrogeological, engineering, and environmental problems in practice. Macroscopic geophysical responses are governed by pore-scale rock properties; therefore, a clear petrophysical understanding of how the pore-scale… read more here.
