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…
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…
Predicting Safe Regions within Lava Flows over Topography
Jack M. Saville, Edward M. Hinton, Herbert E. Huppert
We present a shallow, isothermal, Newtonian model for the transient interaction of lava flows with topography. Numerical integrations and simple mathematical approximations are dep…
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…
Spreading or contraction of viscous drops between plates: single, multiple or annular drops
Keith Moffatt, Howard Guest, Herbert Huppert
The behaviour of a viscous drop squeezed between two horizontal planes is treated by both theory and experiment. When the squeezing force F is constant and surface tension is negle…
Dense Suspension Flow in a Penny-Shaped Crack, Part I : Theory
George R. Wyatt, Herbert E. Huppert
We study the dynamics of proppants carried by fluid driven into an evolving penny-shaped fracture. The behaviour of the slurry flow is investigated in two phases: pressurised injec…
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…
Maximal liquid bridges between horizontal cylinders
Himantha Cooray, Herbert E. Huppert, Jerome A. Neufeld
We investigate two-dimensional liquid bridges trapped between pairs of identical horizontal cylinders. The cylinders support forces due to surface tension and hydrostatic pressure…
Gravity currents in a porous medium at an inclined plane
Dominic Vella, Herbert E. Huppert
We consider the release from a point source of relatively heavy fluid into a porous saturated medium above an impermeable slope. We consider the case where the volume of the result…
