WebWe study a fluid-dynamical model based on a coupled Navier–Stokes–Nernst–Planck–Poisson system. Of special interest are the fluid velocity, concentrations of charged particles ranging from colloidal to nano size and the induced quasi-electrostatic potential, which all depend on an externally applied electrical field.

WebWe study the Nernst-Planck-Navier-Stokes (NPNS) sytem, which models electrodiffusion of ions in a fluid, in the presence of boundaries. Ions suspended in a fluid are advected by the fluid flow and by an electric potential, which results from both an applied potential on the boundary and the distribution of charges carried by the ions. how far is nashville tn to panama city beachWebOn the Nernst-Planck-Navier-Stokes System [Moved Online] Recent Developments in Fluid Dynamics April 12, 2024 - April 30, 2024.
