Power Evaluation for Flutter-based Electromagnetic Energy Harvester Using Cfd Simulations
Structural instability caused by self exciting aerodynamic forces (flutter) can be used as an effective input source for small scale energy harvesters. The self exciting aerodynamic force exerted on a T-shape cantilever causes periodic vibration, which can be converted into electric power through an electromagnetic transducer. Due to the complexities inherent in the fluid-structure interaction ...

متن کاملEnergy Transfer in a Vortex Induced Vibrating Tethered Cylinder System
Flow induced vibration of a tethered body submerged within a uniform flow represents a fundamental example of fluid-structure interaction. However, little research in this field has been undertaken. This paper presents results from a direct numerical simulation of the flow past a tethered cylinder with mass ratio less than 1. The Navier-Stokes and dynamic equations of motion of the cylinder are...
متن کاملFlutter Phenomenon in Flow Driven Energy Harvester–A Unified Theoretical Model for “Stiff” and “Flexible” Materials
Here, we report a stable and predictable aero-elastic motion in the flow-driven energy harvester, which is different from flapping and vortex-induced-vibration (VIV). A unified theoretical frame work that describes the flutter phenomenon observed in both "stiff" and "flexible" materials for flow driven energy harvester was presented in this work. We prove flutter in both types of materials is t...
متن کاملDynamic Simulation of the Harvester Boom Cylinder
Based on the complete dynamic calculation method, the layout, force, and strength of harvester boom cylinders were designed and calculated. Closed simulations for the determination of the dynamic responses of the harvester boom during luffing motion considering the cylinder drive system and luffing angle position control have been realized. Using the ADAMS mechanical system dynamics analysis so...
