Abstract

The multiphysical modeling and simulation of hydrodynamic pressure-driven fluidics and ionic transport in nanopore systems is presented. The physical model couples Poisson equation for electrostatics, steady-state Navier-Stokes equation for laminar flow, and steady-state Nernst-Plank equation for ionic motion. The influence of the nanopore geometry and electrical properties on the induced electrical current is quantitatively investigated. Based on our discussion, we explore the potential strategies for further improving the mechanical-to-electrical energy conversion efficiency, which would enhance the performance of nanopore based power generating devices.
