The present paper describes laboratory tests on steady granular flows down a smooth chute using X-ray radiography. By an original set-up with gate at its end, standing discontinuites in height, velocity and density, namely jumps, were produced during the flows. radiography was successful to get consistent measurements of free-surface density profiles along under different flow states: (nearly) ...

Shock waves and granular vacua are important phenomena for studying the behavior of materials due to dramatic change in flow properties across shock wave particle-free feature at boundary vacuum. In this paper, we use experiment numerical simulation study free-surface past a cylindrical obstacle an inclined chute, where time-dependent development impacting is analyzed both microscopic macroscop...

When a granular mixture involving grains of different sizes is shaken, sheared, mixed, or left to flow, grains tend to separate by sizes in a process known as size segregation. In this study, we explore the size segregation mechanism in granular chute flows in terms of the pressure distribution and granular microstructure. Therefore, two-dimensional discrete numerical simulations of bidisperse ...
