Kinetic energy extraction of a tidal stream turbine and its sensitivity to structural stiffness attenuation (2015)
Journal Article

© 2015 The Authors. The hydrodynamic forces imparted on a tidal turbine rotor, whilst causing it to rotate and hence generate power, will also cause the blades to deform. This deformation will affect the turbine's performance if not included in the e...
