DOI: 10.1039/d2sm01396g
Abstract: Concentrated suspensions of particles at volume fractions (ϕ) ≥ 0.5 often exhibit complex rheological behavior, transitioning from shear thinning to shear thickening as the shear stress or shear rate is increased. These suspensions can be… read more here.

DOI: 10.1063/1.5005966
Abstract: Discontinuous shear thickening observed in many dense suspensions is rather complicated but takes place as a transient. Its details after jamming are still not clear. By using a modified rheometer with an analog-to-digital converter, we… read more here.

Abstract: In the present work, an elastic-core-modified mesoscale dissipative particle dynamics model is proposed, so as to investigate the microstructural evolution dependency on the viscosity in shear thickening fluids. The characteristic of the microstructural evolution in… read more here.

Abstract: We investigate dilation-induced surface deformations in a discontinuous shear thickening (DST) suspension to determine the relationship between dilation and stresses in DST. Video is taken at two observation points on the surface of the suspension… read more here.

Abstract: Granular rheology is experimentally investigated in a vertical Couette-Poiseuille-like channel flow of photoelastic disks, where an erodible bed is sheared intermittently by an upward-moving shear band and a gravity-induced reverse flow. The shear band conforms… read more here.

DOI: 10.1103/physrevfluids.4.074307
Abstract: We present simulations for the steady-shear rheology of a model adhesive dispersion. We vary the range of the attractive forces $u$ as well as the strength of the dissipation $b$. For large dissipative forces, the… read more here.

DOI: 10.1177/1045389x20959458
Abstract: Very concentrated suspensions of iron particles in water or ethylene glycol can be obtained thanks to the use of superplasticizer molecules used in cement industry. At high volume fractions, these suspensions show a discontinuous shear… read more here.
