چکیده

We report experimental measurements of avalanche behavior of thin granular layers on an inclined plane for low volume flow rate. The dynamical properties of avalanches were quantitatively and qualitatively different for smooth glass beads compared to irregular granular materials such as sand. Two scenarios for granular avalanches on an incline are identified and a theoretical explanation for these different scenarios is developed based on a depth-averaged approach that takes into account the differing rheologies of the granular materials.

Avalanche behavior of gravitationally-forced granular layers on a rough inclined plane are investigated experimentally for different materials and for a variety of grain shapes ranging from spherical beads to highly anisotropic particles with dendritic shape. We measure the front velocity, area and the height of many avalanches and correlate the motion with the area and height. We also measure ...

Spectral statistics of global avalanches along granular piles

– In a seminal experiment, Jaeger et al. (Phys. Rev. Lett., 62 (1989) 40) measured the power spectrum of the velocity of avalanches along a granular pile in a rotating drum. Although their findings started an actively discussed debate on whether self-organized criticality rules granular avalanche dynamics, their experimental results have not been explained in theoretical detail yet. By the use ...

Continuum theory of partially fluidized granular flows.

A continuum theory of partially fluidized granular flows is developed. The theory is based on a combination of the equations for the flow velocity and shear stresses coupled with the order-parameter equation which describes the transition between the flowing and static components of the granular system. We apply this theory to several important granular problems: avalanche flow in deep and shal...
