Colloids, grains and dense suspensions: under flow and under arrest.
This Theme Issue reports papers presented at a Discussion Meeting intended to bring together those working on colloids (suspended particles small enough to have strong Brownian motion) with those working on non-Brownian systems such as dry granular matter, dense suspensions of larger particles and pastes. A better understanding of flow and arrest in these systems is of potential value to wide a...
متن کاملThe order-disorder transition of colloidal suspensions under shear flow
We study the order-disorder transition of colloidal suspensions under shear flow by performing Brownian dynamics simulations. We characterize the transition in terms of a statistical property of time-dependent maximum value of the structure factor. We find that its power spectrum exhibits the power-law behaviour only in the ordered phase. The power-law exponent is roughly -2 in the higher frequ...

We characterize the transition in terms of a statistical property of time-dependent maximum value of the structure factor.

متن کاملStability of Concentrated Suspensions under Couette and Poiseuille Flow
The stability of two-dimensional Poiseuille flow and plane Couette flow for concentrated suspensions is investigated. Linear stability analysis of the two-phase flow model for both flow geometries shows the existence of a convectively driven instability with increasing growth rates of the unstable modes as the particle volume fraction of the suspension increases. In addition it is shown that th...
متن کاملHeterogeneous flow kinematics of cellulose nanofibril suspensions under shear.
The rheology of NFC suspensions that exhibited different microstructures and colloidal stability, namely TEMPO and enzymatic NFC suspensions, was investigated at the macro and mesoscales using a transparent Couette rheometer combined with optical observations and ultrasonic speckle velocimetry (USV). Both NFC suspensions showed a complex rheology, which was typical of yield stress, non-linear a...
