Medientyp: E-Artikel Titel: Motion of a Ferrofluid in a Periodic Magnetic Field due to Surface Deformation Beteiligte: Popp, Jana; Zeidis, Igor; Zimmermann, Klaus; Böhm, Valter; Gärtner, Ralf Erschienen: Wiley, 2011 Erschienen in: PAMM Sprache: Englisch DOI: 10.1002/pamm.201110322 ISSN: 1617-7061 Schlagwörter: General Medicine Entstehung: Anmerkungen: Beschreibung: <jats:title>Abstract</jats:title><jats:p>The article considers a plane flow of an incompressible, viscous magnetizable fluid. Cause of the flow is an alternating magnetic field, which consequently affects the free surface to periodical deformation. The proof of a peristaltic material transport is desired. The STOKES approximation for creeping flows and the two‐dimensional continuity equation serve for governing equations. The methods used include power series expansion with regard to the small ratio of ε perturbed and unperturbed fraction of the magnetic field. The analytical result is discussed with regard to functional parameters. (© 2011 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)</jats:p> Zugangsstatus: Freier Zugang
