Steady flows in networks of microfluidic channels: building on the analogy with electrical circuits
Comptes Rendus. Physique, Volume 5 (2004) no. 5, pp. 539-546.

This paper gathers comments and elaborations on the classical representation of networks of microfluidic channels in terms of equivalent electrical circuits. Basics on pressure-driven and electro-osmotic flows are first recalled. A unified formalism for hydrodynamic and electro-kinetic effects in networks of arbitary topology is then presented. Eventually, comments on the representation of pumps by generators are proposed.

Différents aspects de la représentation de réseaux de canaux microfluidiques par des circuits électriques équivalents sont discutés. Après un rappel sur les écoulements par gradient de pression et par électro-osmose, un formalisme général est proposé pour les effets hydrodynamiques et électrocinétiques dans des réseaux de topologies variées. Suivent quelques remarques sur la description de pompes par des générateurs équivalents.
