Projektbeschreibung
Austauschprozesse an der Grenzfläche zwischen freien Strömungen und Strömungen in porösen Medien treten in vielfältiger Weise bei umweltrelevanten, technischen und biomechanischen Systemen auf. Die primären Ziele dieses Projekts sind (i) eine umfangreiche Analyse zur Verbesserung des theoretischen Verständnisses, (ii) die Entwicklung von Lösungsansätzen, die Mehrphasenströmungs- und Transportvorgänge einschließen, und (iii) die Untersuchung des Einflusses der grenzflächenbedingten Vorgänge sowohl auf die Strömungen im porösen Medium als auch auf die freie Strömung für unterschiedliche Applikationen.
