We identify the sequence of microstructural changes that characterize the evolution of an attractive particulate gel under flow and discuss their implications on macroscopic rheology. Dissipative particle dynamics is used to monitor shear-driven evolution of a fabric tensor constructed from the ensemble spatial configuration of individual attractive constituents within the gel. By decomposing this tensor into isotropic and nonisotropic components we show that the average coordination number…

Rheological manifestation of microstructural change of colloidal gel under oscillatory shear flow

The rheological manifestation of intra-cycle microstructural change of a model colloidal gel under oscillatory shearing is studied with Brownian dynamics simulation and a fully quantitative sequence

Multiscale Nature of Thixotropy and Rheological Hysteresis in Attractive Colloidal Suspensions under Shear.

This work investigates hysteresis across different length scales: from particle-level local measurements of coordination number (microscale), to the appearance of density and velocity fluctuations (mesoscale), and up to the shear stress response to an imposed deformation (macroscale).

Time-resolved microstructural changes in large amplitude oscillatory shear of model single and double component soft gels

Soft particulate gels can reversibly yield when sufficient deformation is applied, and the characteristics of this transition can be enhanced or limited by designing hybrid hydrogel composites. While

A hydrodynamic model for discontinuous shear-thickening in dense suspensions

Restricted sliding or rotational motion of colloidal particles plays a key role in the emergence of discontinuous shear thickening (DST). From viscometric functions to the number of contacting

Mapping thixo-elasto-visco-plastic behavior

A century ago, and more than a decade before the term rheology was formally coined, Bingham introduced the concept of plastic flow above a critical stress to describe steady flow curves observed in

Mapping Thixo-Visco-Elasto-Plastic Behavior

Pressure-driven flows of a thixotropic viscoplastic material: Performance of a novel fluidity-based constitutive model

This paper examines pressure-driven tube flows of inelastic yield-stress materials with thixotropic effects. In contrast to previous works based on structural kinetic models, we employ a

Transient dynamics of soft particle glasses in startup shear flow. Part I: Microstructure and time scales

The rheology and microstructure of soft particle glasses during startup flow are studied using three-dimensional particle dynamics simulations at different particle volume fractions and shear rates.

Rheological investigation of gels formed by competing interactions: A numerical study.

A numerical investigation of the rheology of equilibrium gels in which a short-range depletion is complemented by a long-range electrostatic interaction and it is found that steady states corresponding to the same Péclet number, obtained by different combinations of shear rate and solvent viscosity, show identical structural and rheological properties.

A Thermodynamically Consistent, Microscopically-Based, Model of the Rheology of Aggregating Particles Suspensions

In this work, we outline the development of a thermodynamically consistent microscopic model for a suspension of aggregating particles under arbitrary, inertia-less deformation. As a



Role of isostaticity and load-bearing microstructure in the elasticity of yielded colloidal gels

These studies show that bond breakage occurs mainly due to the erosion of rigid clusters that persist far beyond the yield strain, and find a power-law scaling of the elastic modulus with the stress-bearing volume fraction that is valid over a range of volume fractions and gelation conditions.

Microstructural response of dilute colloidal gels to nonlinear shear deformation

The time-resolved microstructural response of dilute, depletion-induced colloidal gels prepared in a density and refractive index matched solvent, to nonlinear shear deformation was investigated in

Stress localization, stiffening, and yielding in a model colloidal gel

We use numerical simulations and an athermal quasistatic shear protocol to investigate the yielding of a model colloidal gel. Under increasing deformation, the elastic regime is followed by a

Shear-induced structuration of confined carbon black gels: steady-state features of vorticity-aligned flocs

Various dispersions of attractive particles are known to aggregate into patterns of vorticity-aligned stripes when sheared in confined geometries. We report a thorough experimental investigation of

Microscopic picture of cooperative processes in restructuring gel networks.

It is shown that consequences of local bond breaking propagate along the gel network over distances larger than the average mesh size, providing the missing microscopic explanation for why nonlocal constitutive relations are necessary to rationalize the nontrivial mechanical response of colloidal gels.

Rheo-PIV Analysis of the Yielding and Flow of Model Waxy Crude Oils

Waxes are a commonly encountered precipitate that can result in the gelation of crude oils and cessation of flow in pipelines. In this work, we develop a model wax–oil system that exhibits

Spatiotemporal oscillations and rheochaos in a simple model of shear banding.

By varying the strength of instability and the applied shear rate, a simple model of shear banding is studied in which the flow-induced phase is destabilized by coupling between flow and microstructure (wormlike micellar length).

Simultaneous rheological and velocity profile measurements are performed in a smooth Couette geometry on laponite suspensions seeded with glass microspheres and undergoing the shear-induced

Imaging the Microscopic Structure of Shear Thinning and Thickening Colloidal Suspensions

By combining fast confocal microscopy with simultaneous force measurements, this work systematically investigates a suspension’s structure as it transitions through regimes of different flow signatures and shows that shear thinning results from the decreased relative contribution of entropic forces and shear thickening arises from particle clustering induced by hydrodynamic lubrication forces.
