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…
