Public ISBD [article]  inTransactions of the ASME . Journal of fluids engineering > Vol. 130 N° 8 (Août 2008) . - 8 p. Titre : An analytical method for dielectrophoresis and traveling wave dielectrophoresis generated by an n-phase interdigitated parallel electrode array Type de document : texte imprimé Auteurs : Hongjun Song, Auteur ; Dawn J. Bennett, Auteur Année de publication : 2009 Article en page(s) : 8 p. Note générale : Fluids engineering Langues : Anglais (eng) Mots-clés : Force  electric fields  waves  electrodes  boundary-value problems  travel  potential  equations  computational fluid dynamics Résumé : In this paper, we present an analytical method for solving the electric potential equation with the exact boundary condition. We analyze the dielectrophoresis (DEP) force with an n-phase ac electric field periodically applied on an interdigitated parallel electrode array. We compare our analytical solution with the numerical results obtained using the commercial software CFD-ACE . This software verifies that our analytical method is correct for solving the problem. In addition, we compare the analytical solutions obtained using the exact boundary conditions and the approximate boundary conditions. The comparison shows that the analytical solution with the exact boundary condition gives a more accurate analysis for DEP and traveling wave DEP forces. The DEP forces of latex beads are also investigated with different phase arrays for (n=2,3,4,5,6).
