Zusammenfassung
In this work, the benefits of employing the partitioned approach in fluid-structure interaction simulations are demonstrated in four different examples: Simulations of a floating offshore wind turbine and a wave energy converter are used to analyze dynamic effects and improve the structural design. A multilayered submersible mixer validates the simulations by assessing local strains, thrust, and torque. Finally, an anisotropic ship propeller made of carbon-reinforced polymer is optimized with an evolutionary algorithm based on coupled simulations concerning efficiency, thrust, and cavitation.
