Vortex Induced Vibration

Vortex-induced vibration (VIV) describes the oscillations of structures interacting with fluid flows, a phenomenon crucial for understanding and mitigating structural damage in various engineering applications. Current research focuses on developing accurate and efficient predictive models, employing techniques like physics-informed neural networks and graph neural networks to capture the complex fluid-structure interactions, often enhanced by transfer learning to reduce data requirements. These advancements improve the design of structures resistant to VIV, impacting fields ranging from building design (e.g., tuned mass dampers for earthquake resistance) to underwater robotics (e.g., improved sensor design for aquatic vehicles).
