摘要：

We examine the rheological behavior of n alkanes, in particular n decane (C10H22) and n eicosane (C20H42). We observe, for the first time in a molecular dynamics simulation, the phenomenon of shear thickening. Over the accessible range of strain rates we see a regime of shear thinning, and then shear thickening in both fluids. The transition from shear thinning to shear thickening is correlated with a qualitative change in the single molecule properties; in particular the distribution of alignment angles and end-to-end distances.
