Query: Population-balance description of shear-induced clustering, gelation and
  suspension viscosity in sheared DLVO colloids   Application of shear flow to charge-stabilized aqueous colloidal suspensions
is ubiquitous in industrial applications and as a means to achieve controlled
field-induced assembly of nanoparticles. Yet, applying shear flow to a
charge-stabilized colloidal suspension, which is initially monodisperse and in
quasi-equilibrium leads to non-trivial clustering phenomena (and sometimes to a
gelation transition), dominated by the complex interplay between DLVO
interactions and shear flow. The quantitative understanding of these strongly
nonequilibrium phenomena is still far from being complete. By taking advantage
of a recent shear-induced aggregation rate theory developed in our group, we
present here a systematic numerical study, based on the governing master
kinetic equation (population-balance) for the shear-induced clustering and
breakup of colloids exposed to shear flow. In the presence of sufficiently
stable particles, the clustering kinetics is characterized by an initial very
slow growth, controlled by repulsion. During this regime, particles are slowly
aggregating to form clusters, the reactivity of which increases along with
their size growth. When their size reaches a critical threshold, a very rapid,
explosive-like growth follows, where shear forces are able to overcome the
energy barrier between particles. This stage terminates when a dynamic balance
between shear-induced aggregation and cluster breakage is reached. It is also
observed that these systems are characterized by a cluster mass distribution
that for a long time presents a well-defined bimodality. The model predictions
are quantitatively in excellent agreement with available experimental data,
showing how the theoretical picture is able to quantitatively account for the
underlying nonequilibrum physics.
