Nanofluidic flow with polymers

ORAL

Abstract

We study the behavior of a single polymer in fluid flow in a periodic array of nanopits, which has also been a subject of recent experiments. We employ an explicit solvent based on the lattice Boltzmann method that reproduces the fluctuating Navier-Stokes equation with a well-defined temperature. The fluid functions as a heat bath for the polymer, whose constituents are coupled realistically to the solvent through a frictional force.
