Abstract
Résumé

A whole boundary-integral formulation is proposed to determine the rigid-body motions of two solid and insulating particles, freely-suspended in a metal liquid and subject to uniform ambient electric and magnetic fields. As revealed by our numerical results, particle–particle interactions may become significant for close enough bodies.

En s'appuyant sur une formulation intégrale, on détermine le mouvement de deux particules solides, isolantes et plongées dans un métal liquide, sous l'action conjuguée d'un champ électrique et d'un champ magnétique uniformes. Les premiers résultats numériques montrent que les interactions entre les particules peuvent être très fortes lorsque ces dernières s'avèrent proches.
