Performance of a Closed Cycle Power Takeoff for a Shore-Based Wave Energy Device

A promising class of devices for ocean wave energy conversion is called the oscillating water column in which power transferred to an airflow that rotates a turbine. closed cycle takeoff (CCPTO), air forced through two valves and turbine, has main benefits such system: it allows unidirectional smooths large variations pressure due irregular (i.e., polychromatic) seas. This paper presents design CCPTO shore-based installation, with particular attention paid The entire system simulated reduced order model range sea states estimate operating conditions It found drop modest but strongly dependent on tide chamber geometry. geometry turbine initially developed 1D preliminary blades then performance analysed refined using Reynolds Averaged Navier–Stokes simulations. process conducted based climate real-life installation located Mutriku (Spain). displays efficient over wide obtained. overall this as part assessed leads output ∼1500 kWh one month at plant Spain. concluded deserves further development any fixed system.
