Medientyp: E-Artikel Titel: Modelling of Surfactant Concentration in a Coupled Bulk Surface Problem Beteiligte: Hahn, Andreas; Held, Kristin; Tobiska, Lutz Erschienen: Wiley, 2014 Erschienen in: PAMM Sprache: Englisch DOI: 10.1002/pamm.201410250 ISSN: 1617-7061 Schlagwörter: General Medicine Entstehung: Anmerkungen: Beschreibung: <jats:title>Abstract</jats:title><jats:p>Surface active agents (surfactants) are on high interest for physical and chemical industries. Their presence lowers the surface tension of fluids. This is used to achieve special flow properties. These mechanisms are not only influenced by the overall amount of surfactant. They highly depend on the local surfactant distribution. The surfactant concentration is modeled by two convection diffusion equations, one in the bulk and the other on its surface. Adsorption‐ and desorption processes are included and lead to a (non linear) coupling of both equations. We present a numerical scheme for solving the coupled problem. Additionally, first analytical results will be given. (© 2014 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)</jats:p> Zugangsstatus: Freier Zugang
