Fig. 1: Shear thinning in several different supercooled liquids.
From: Universal mechanism of shear thinning in supercooled liquids
We present data for the Gaussian core model (GCM), the Kob-Andersen (KA) model, the soft sphere (SS) model, the two-dimensional SS (2DSS) model, and the van Beest-Kramer-van Santen (BKS) model. a Plots of τα/τα0, η/η0, or \({D}^{-1}/{D}_{0}^{-1}\) are shown as a function of \(\dot{\gamma }/{\dot{\gamma }}_{c}\). The temperature is T = 2.9 × 10−6 (GCM), 0.45 (KA), 0.275 (SS), 0.577 (2DSS), and 0.511 (BKS), all above the dynamical transition temperature Tc. The black line represents \({\tau }_{\alpha }/{\tau }_{\alpha 0},\,\eta /{\eta }_{0},\,{D}^{-1}/{D}_{0}^{-1}=1\). The blue line represents \(\propto {\dot{\gamma }}^{-0.7}\), while the red line refers to \(\propto {\dot{\gamma }}^{-1}\) (advection scenario). The vertical dotted line indicates the onset shear rate \({\dot{\gamma }}_{c}\). b \({\dot{\gamma }}_{c}\) is plotted against τα0 or η0. The blue line presents \({\dot{\gamma }}_{c}\propto {\tau }_{\alpha 0}^{-1.4}\) or \({\eta }_{0}^{-1.4}\), while the red line refers to \({\dot{\gamma }}_{c}={\tau }_{\alpha 0}^{-1}\) or \({\eta }_{0}^{-1}\) (advection scenario). The data for the SS model are extracted from ref. 18, the 2DSS model from ref. 17, and the BKS model from ref. 19.
