Fig. 3: Torque versus platelet orientation.
From: Hydrodynamic slip can align thin nanoplatelets in shear flow
Non-dimensional hydrodynamic torque \(T/({a}^{2}w\dot{\gamma }\eta )\) versus platelet inclination angle α. Symbols correspond to MD simulations for a monolayer with aspect ratio b/a = 0.15, half length a = 1.7 nm and slip length λ = (60 ± 5) nm (disks) and a bilayer with aspect ratio b/a = 0.25, half length a = 1.7 nm and slip length λ = (60 ± 5) nm (squares); red lines are BI calculations for the corresponding values of λ/b and b/a. Error bars correspond to the standard deviation from 10 simulations of 0.4 ns. The dashed lines mark the inclination angle αc for which the hydrodynamic torque is zero. The blue line corresponds to BI calculations in the case of a monolayer with no-slip boundary condition. Insert: Torque vs platelet inclination angle for α ∈ [0, π].
