Electrophoresis of a 2-particle cluster near a plane boundary
Comptes Rendus. Mécanique, Volume 331 (2003) no. 6, pp. 401-406.

Particle–boundary and particle–particle interactions in Electrophoresis are examined by considering a 2-particle cluster near a plane boundary. The advocated treatment holds for two insulating particles of arbitrary shapes and zeta potential functions and resorts to 13 boundary-integral equations. Preliminary results reveal that, depending upon the addressed velocity nature (translational or angular), wall–particle may be stronger or weaker than particle–particle interactions.

On examine l'électrophorèse d'une particule isolante, sous l'action d'un champ électrique uniforme E, en présence d'une seconde particule isolante et d'une paroi plane parfaitement conductrice et normale à E ou isolante et parallèle à E. La méthode préconisée utilise 13 équations intégrales de frontière et on montre que, selon la nature (translation ou rotation) de la vitesse examinée, les intéractions paroi–particule peuvent être plus fortes ou moindres que les intéractions particule–particule.
