On the Drag Coefficient Universality of a Rough Grain in Creeping Flow
Si Suo, Deheng Wei, Budi Zhao +2
Controversy exists regarding whether grain morphology reduces or enhances the drag of a single grain in creeping flows; further complication occurs when orientation dependence for…
Contact behaviour of simulated rough spheres generated with spherical harmonics
Deheng Wei, Chongpu Zhai, Dorian A. H. Hanaor +1
Normal contact behaviour between non adhesive fractal rough particles is studied using a finite element method (FEM). A series of spherical grain surfaces with distinguished roughn…
An unexplored valley of binary packing: The loose jamming state
Si Suo, Chongpu Zhai, Minglong Xu +2
We present a theoretical prediction on random close packing factor ϕ_RCP^b of binary granular packings based on the hard-sphere fluid theory. An unexplored regime is unravelled, wh…
Stress-dependent electrical transport and its universal scaling in granular materials
Chongpu Zhai, Dorian Hanaor, Gwénaëlle Proust +1
We experimentally and numerically examine stress-dependent electrical transport in granular materials to elucidate the origins of their universal dielectric response. The ac respon…
Measurement of normal contact stiffness of fractal rough surfaces
Chongpu Zhai, Sébastien Bevand, Yixiang Gan +4
We investigate the effects of roughness and fractality on the normal contact stiffness of rough surfaces. Samples of isotropically roughened aluminium surfaces are considered. The…
