Abstract

In this work, the performance of biomimetic device that consists of including a rotating, vertically mounted, biomimetic wing, supported by an arm linked at a pivot point on the mid-chord is evaluated using a numerical model is considered and results are presented concerning  the  performance.  Activated  by  a  controllable  self-pitching  motion,  the  system performs angular oscillations around the vertical axis in incoming flow. The performance of the above flapping-foil, biomimetic flow energy harvester, is calculated and the results are compared  against  experimental  data.  By  systematical  application  of  the  model  the  power extraction  and  efficiency  of  the  system  is  presented  for  various  cases  including  different geometric, mechanical, and kinematic parameters, and the optimal performance of the system is  determined.  Also  comparisons  of  the  calculated  performance  are  presented  against predictions for other tidal energy devices, such as the stream energy converters based on the vortex-induced angular oscillations of a cylinder.
