Scaling of granular column collapses on inclined planes
Teng Man, Herbert E. Huppert, Sergio Andres Galindo-Torres
Granular column collapse is a simple but important problem to the granular material community, due to its links to dynamics of natural hazards, such as landslides and pyroclastic f…
Shear viscosity scaling of granular suspensions across dilute to dense regimes
Zaohui Zhang, Teng Man, Herbert E. Huppert +1
In this letter, following an extensive experimental validation, we perform constant-volume shearing simulations of non-Brownian granular suspensions using the discrete element meth…
Mean Stress Tensor of Discrete Particle Systems in Submerged Conditions
Zhuan Ge, Teng Man, Sergio Andres Galindo-Torres
The mean stress tensor is essential to investigate the dynamics of granular material. In this paper, we use Hamilton's principle of least action to derive the averaged stress tenso…
Unifying Lengthscale-Based Rheology of Dense Granular-Fluid Mixtures
Zhuan Ge, Teng Man, Herbert E. Huppert +2
In this communication, we present a new lengthscale-based rheology for dense sheared particle suspensions as they transition from inertial- to viscous-dominated. We derive a length…
Axisymmetric column collapses of bi-frictional granular mixtures
Teng Man, Zaohui Zhang, Herbert E. Huppert +1
The behavior of granular column collapses is associated with the dynamics of geohazards, such as debris flows, landslides, and pyroclastic flows, yet its underlying physics is stil…
Transient Rheology of Immersed Granular Materials
Zhuan Ge, Teng Man, Herbert E. Huppert +1
In this letter, we investigate the transient rheological behavior of immersed granular flows using both experiments of submerged granular column collapses and corresponding numeric…
Influence of Cross-section Shape on Granular Column Collapses
Teng Man, Herbert E. Huppert, Zaohui Zhang +1
We investigate granular column collapses with different column cross-sections and associate the cross-section shape influence with a finite-size analysis. Previous research, confin…
Friction-dependent rheology of dry granular systems
Teng Man, Pei Zhang, Zhuan Ge +2
Understanding the rheology of granular assemblies is important for natural and engineering systems, but the relationship between inter-particle friction (or microscopic friction) a…
Finite-Size Analysis of the Collapse of Dry Granular Columns
Teng Man, Herbert E. Huppert, Ling Li +1
In this letter, we focus on the size effect of granular column collapses, which are potentially connected to the dynamics of complex geophysical flows, even if the link between mic…
Deposition Morphology of Granular Column Collapses
Teng Man, Herbert E. Huppert, Ling Li +1
Granular column collapses result in an array of flow phenomena and deposition morphologies, the understanding of which brings insights into studying granular flows in both natural…
Gyratory Shearing Compaction of Granular Materials
Teng Man
In this letter, instead of investigating the compaction of granular materials under tapping or cyclic shearing, we focused more on the gyratory shearing compaction, where particles…
