Abstract
The behavior of a liquid-particle suspension induced to sheared motion
was analyzed by numerical simulations. When the velocity (strain) of the
suspension began to increase, its viscosity first stayed almost
constant, but increased then rapidly to a clearly higher level. This
increase in viscosity is shown to be related to formation of clusters of
suspended particles. Clusters are shown to increase the viscosity by
enhanced momentum transfer though clustered particles. This is the
mechanism behind the strain-hardening phenomenon observed in
small-strain experiments on liquid-particle suspensions.
