Nonequilibrium molecular dynamics simulations of the structure and momentum transfer coefficient, for an interface stabilized by HnTn block-copolymers (n = 5, 10, 15), subjected to a shear field with the gradient direction perpendicular to the interface: (a) geometry of the problem, (b) density and x-component of velocity as a function of vertical position z; (c) extrapolated bulk velocities and surface velocity; (d) momentum transfer coefficient ξxx as a function of shear rate; the inset shows the product of ξxx with block size n.
