摘要
In the realm of mechanical engineering, the accurate prediction of fluid-structure interaction (FSI) is paramount for the design and analysis of systems where fluids and structures coexist and interact. This research paper presents a novel approach to address complex FSI problems using coupled multiphysics simulation through Finite Element Analysis (FEA). The proposed methodology integrates advanced computational algorithms to capture the intricate interplay between fluid dynamics and structural mechanics, ensuring a more holistic representation of real-world scenarios. The developed framework was tested on a variety of benchmark problems, ranging from aeroelastic flutter in aircraft wings to blood flow-induced stresses in arterial walls. Results indicate a significant enhancement in prediction accuracy and computational efficiency compared to traditional decoupled methods. Furthermore, the study delves into the challenges faced during the coupling process, offering solutions to mitigate numerical instabilities and enhance convergence rates. The findings of this research not only pave the way for improved design and safety protocols in industries such as aerospace, biomedical, and civil engineering but also underscore the potential of Multiphysics simulation in unravelling the complexities of the natural world.
