Theory of rheology of colloidal dispersions

This brief review contains a survey of recent literature on theory of rheology of colloidal dispersions. Areas of active research are highlighted, such as approximations for many body interactions in weakly sheared dispersions and the flow-induced microstructural distortions in more strongly sheared dispersions. The former approach seeks to capture the viscosity increase on increasing particle concentration, whereas the latter explains shear thinning and shear thickening.
