What are the efficiencies of the devices?

Published by

  • In Matt Folley and al.’s[i] study on the OWSC, the efficiency of the device was based on its capture factor.
  • The maximum capture factor is determined by plotting the root mean square (RMS) of the braking torque against the capture factor.
  • The optimum torque occurs when the sum of the reflected and radiated wave power and the power lost to viscosity and turbulence is minimal.
  • In the North Atlantic wave climate, Matt Folley and his peersii find that the average capture factor is 0.46.
