Relaxation of Dense Suspension
Dense suspensions exhibit complex rheological behavior by behaving liquid-like at low shear stresses and solid-like at high shear stresses. The microscopic interactions between individual particles create non-Newtonian macroscopic behaviors by transitioning from hydrodynamic interactions to …

Relaxation behavior of dense suspensions
Dense suspensions of solid particles in Newtonian fluids exhibit a variety of non-Newtonian behaviors depending on the shear stress applied to the suspension and the particle mass fraction ([mathematical symbol]m). Suspensions at sufficiently high fm shear-thicken dramatically and eventually shear …

Computer simulation studies of dense suspension rheology. Computational studies of model sheared fluids; elucidation, interpretation and description of the observed rheological behaviour of simple colloidal suspensions in the granulo-viscous domain by Non-Equilibrium Particulate Dynamics.
… flow phenomenology commonly seen in dense suspensions are investigated by particulate-dynamics computer-simulations. The objectives of these investigations are: (i) to establish the origins of various aspects of dense suspension rheology such as shear-thinning, shear thickening and …

Dynamic behavior of unsteady turbulent motion in pipe flows of dense gas-solid suspensions
Unsteady stratified motions in dense gas-solid suspension in horizontal pipe flows at low velocities have been observed, but the means for predicting these motions are lacking. For a dense suspension, the effects of particle-particle interaction, the damping of fluid motion by particles and the …

Stokes flows near boundaries: bacteria, corners, and pumps
… direction (when viewed from above) ahead of a dense suspension of bacteria on a moist surface. We quantitatively test a hypothesis that this flow is due to the action of cells stalled at the edge of a colony which extend their flagella outwards, moving fluid over a substrate. The model provides …

An investigation of heat stable milk chocolate by addition of glycerol
… heat stable chocolate. Milk chocolate (MC) is a dense suspension consisting of cocoa solids, sugar and milk powder dispersed in a continuous fat phase of cocoa butter and milk fat. Heat stable milk chocolate (HSMC) is chocolate that does not flow at temperatures between 35-40 °C, when traditional …
