Flutter Instability in an Internal Flow Energy Harvester [PDF]
, 2020 Vibration-based flow energy harvesting enables robust, in-situ energy extraction for low-power applications, such as distributed sensor networks. Fluid-structure instabilities dictate a harvester's viability since the structural response to the flow determines its power output.

Life-cycle assessment for flutter probability of a long-span suspension bridge based on field monitoring data [PDF]
arXiv, 2021 Assessment of structural safety status is of paramount importance for existing bridges, where accurate evaluation of flutter probability is essential for long-span bridges. In current engineering practice, at the design stage, flutter critical wind speed is usually estimated by the wind tunnel test, which is sensitive to modal frequencies and damping ...
