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…
Tailoring porous media for controllable capillary flow
MingchaoLiu, Si Suo, Jian Wu +2
Hypothesis Control of capillary flow through porous media has broad practical implications. However, achieving accurate and reliable control of such processes by tuning the pore si…
Scalable Surface Area Characterization by Electrokinetic Analysis of Complex Anion Adsorption
Dorian A. H. Hanaor, Maliheh Ghadiri, Wojciech Chrzanowski +1
By means of the in situ electrokinetic assessment of aqueous particles in conjunction with the addition of anionic adsorbates, we develop and examine a new approach to the scalable…
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…
Two-dimensional modeling of the self-limiting oxidation in silicon and tungsten nanowires
Mingchao Liu, Peng Jin, Zhiping Xu +3
Self-limiting oxidation of nanowires has been previously described as a reaction- or diffusion-controlled process. In this letter, the concept of finite reactive region is introduc…
Compressive performance and crack propagation in Al alloy/Ti2AlC composites
D. A. H. Hanaor, L. Hu, W. H. Kan +4
Composite materials comprising a porous Ti2AlC matrix and Al 6061 alloy were fabricated by a current-activated pressure assisted melt infiltration process. Coarse, medium and fine…
The effects of packing structure on the effective thermal conductivity of granular media: A grain scale investigation
Weijing Dai, Dorian Hanaor, Yixiang Gan
Structural characteristics are considered to be the dominant factors in determining the effective properties of granular media, particularly in the scope of transport phenomena. To…
Modes of wall induced granular crystallisation in vibrational packing
Weijing Dai, Joerg Reimann, Dorian Hanaor +2
Granular crystallisation is an important phenomenon whereby ordered packing structures form in granular matter under vibration. However, compared with the well-developed principles…
Dynamics of Viscous Entrapped Saturated Zones in Partially Wetted Porous Media
Shuoqi Li, Mingchao Liu, Dorian Hanaor +1
As a typical multiphase fluid flow process, drainage in porous media is of fundamental interest in nature and industrial applications. During drainage processes in unsaturated soil…
Dynamic contact angle hysteresis in liquid bridges
Zhang Shi, Yi Zhang, Mingchao Liu +2
This work presents a combined experimental and theoretical study of dynamic contact angle hysteresis using liquid bridges under cyclic compression and stretching between two identi…
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…
Solution based synthesis of mixed phase materials in the Li2TiO3 - Li4SiO4 system
Dorian A. H. Hanaor, Matthias H. H. Kolb, Yixiang Gan +2
As candidate tritium breeder materials for use in the ITER helium cooled pebble bed, ceramic multiphasic compounds lying in the region of the quasi-binary lithium metatitanate- lit…
Measurement of normal contact stiffness of fractal rough surfaces
