Coupling Heterarchical Granular Dynamics and Computational Fluid Dynamics
Jiahuan Li, Shivakumar Athani, Alistair Gillespie +3
Granular flows in ambient fluids exhibit grain-size-dependent segregation, which is difficult to capture efficiently with existing models, especially in large-scale systems involvi…
Scale dependence of segregation patterns in the filling of silos
Shivakumar Athani, Benjy Marks, François Guillard +2
Size segregation in granular flows is a well-known phenomenon: laboratory experiments consistently show that large particles migrate toward silo walls during filling, while smaller…
Heterarchical Granular Dynamics
Benjy Marks, Shivakumar Athani, Itai Einav
The two most commonly used methods to model the behaviour of granular flows are discrete element and continuum mechanics simulations. These approaches concentrate on the determinis…
A Thermodynamic Treatment\\ of Partially Saturated Soils \\ Revealing the Structure of Effective Stress
Yimin Jiang, Itai Einav, Mario Liu
A rigorous thermodynamic treatment of partially saturated soils is developed using a minimal number of assumptions. The derivation is carried out in a way that does not require to…
Static friction at fractal interfaces
Dorian Hanaor, Yixiang Gan, Itai Einav
Tribological phenomena are governed by combined effects of material properties, topology and surface-chemistry. We study the interplay of multiscale surface structures with molecul…
Contact mechanics of fractal surfaces by spline assisted discretisation
Dorian Hanaor, Yixiang Gan, Itai Einav
We present a newly developed approach for the calculation of interfacial stiffness and contact area evolution between two rough bodies exhibiting self affine surface structures. Us…
