The Simplest Viscous Flow

Hoover William G., Hoover Carol G.

We illustrate an atomistic periodic two-dimensional stationary shear flow, u_x = ( x˙ ) = E˙y, using the simplest possible example, the periodic shear of just two particles! We use a short-ranged “realistic” pair potential, ...

Minimal Energy Dissipation Rate and Director Orientation Relative to External Dissipative Fields such as Temperature and Velocity Gradients in Nematic and Cholestric Liquid Crystals

Sarman Sten, Wang Yong-Lei, Laaksonen Aatto

The purpose of this review article is to summarize observations accumulated over the years on director alignment phenomena in nematic and cholesteric liquid crystals by molecular dynamics simulation of molecular model ...
