Keywords:
electrodialysis, desalination, criteria numbers, Nernst-Planck-Poisson equations, Navier- Stokes equations, similarity theory.Abstract
Subject of research — transport processes in electro-membrane systems; theme — the
electroconvection; purpose — the development of scaling theory of transport processes in electro-
membrane systems. The research method — mathematical and numerical modeling.
The results of the work. A theory of similarity introduced similarity criteria, clarify their physical
meaning and examples. Recommendations are given for the physical and computational experiments.
Offer some nontrivial similarity criteria using which investigated the effect of some parameters on
electroconvection.
Proposed local criterial number allows you to enter the threshold curve electroconvection for electro
systems with forced convection. Given the physical meaning of the threshold curve.
Scope of results: theoretical and experimental studies of transport processes in electro systems based
electroconvection, simulation and optimization of geometrical and technological parameters of the
electrodialysis desalination devices.
