Als Fluid-Struktur-Kopplung (englisch fluid-structure interaction) wird im Ingenieurwesen die Berücksichtigung der gegenseitigen Beeinflussung von Struktur und Strömung bezeichnet. Dabei werden numerische Verfahren zur Strömungs- und Strukturberechnung miteinander gekoppelt. Die wechselseitige Beeinflussung von Struktur und Strömung ist ein interessantes, in Natur und Technik häufig vorkommendes Phänomen. Sie tritt an elastischen, leicht verformbaren, schwingfähigen, drehbar oder verschiebbar gelagerten, umströmten oder durchströmten Strukturen auf.Die Ablösung von Wirbeln kann die umströmte Struktur in merkliche Schwingungen versetzen. Strömungsinduzierte Schwingungen kommen z. B. an Flugzeugflügeln, an Propellerblättern, aber auch bei der Umströmung von Bauwerken vor. Sind die Schwingungen groß genug, beeinflussen sie im Gegenzug die Strömung. Weitere populäre Beispiele für eine Fluid-Struktur-Wechselwirkung sind die Strömung in Blutgefäßen oder die Umströmung von Herzklappen. (de) Fluid–structure interaction (FSI) is the interaction of some movable or deformable structure with an internal or surrounding fluid flow. Fluid–structure interactions can be stable or oscillatory. In oscillatory interactions, the strain induced in the solid structure causes it to move such that the source of strain is reduced, and the structure returns to its former state only for the process to repeat.
