Abstract

Electrodialyis is a process engineering technique in which electro-chemical potentials are used to separate different substances. It has been used in a couple of engineering application areas for many years already. Recently, sea water desalination by an electrodialytic process became of interest, as the concept offers a very efficient way for the generation of drink water from sea water. Although this way of drink water generation is known to be energetic efficient, the basic mechanisms in a desalination plant are not well known. In this paper we describe our approach to integrated, multiphysics simulation of such a process. We focus on the hydrodynamic part of a desalination stack and present a scalable simulation environment for mass transfer and hydrodynamics by means of a multicomponent Lattice Boltzmann method. Performance measurements on state of the art for realistic simulation setups on supercomputers are presented.
