1 Description

This code solves the continuity and momentum equations along with the transport equations for cations and anions and the Poisson equation. The electrostatic equations are coupled to the fluid flow equations through the convective terms in ionic transport equations. The ionic transport equations are coupled to each other through the electrostatic Poisson equation. This solver is written to address the internal electrohydrodynamic flow. However, since this code is developed from the InterFOAM solver, it can easily be used for the external electrohydrodynamic flow and can also address the multiphase flow.

The fixed gradient boundary condition library in OpenFOAM is modified to create a customized gradient boundary condition for the ions that can be updated in each iteration. This boundary conditions accounts for the flux of counter-ions at the electrode surface due to the faradaic reactions.
