Piezoelectric Energy Harvesting from a Pitch-Plunge Aerofoil in Compressible Flow, the Euler Full-Order Model, Strip Theory and the Reduced Models Compared

A piezoelectric transducer embedded in a pitch-plunge aerofoil with a finite-mass trailingedge flap converts the limit-cycle oscillation that follows flutter into electrical power. The design findings for such a harvester have so far been obtained with incompressible strip theory, whose aerodynamic
