The study used representative sea states of the Monterey Bay, California, USA. The geometry of the coaxial ducted OWC was hydrodynamically optimized using a frequency domain approach considering a linear air turbine. Afterwards, a time domain analysis was carried out for the system equipped with a biradial turbine. The turbine rotor diameter and the optimum generator\u2019s control curves were determined, based on results for representative sea states. Results show that mean power output fulfills the requirement for oceanographic applications (300\u2013500W) using a turbine rotor diameter of 0.25 m. Furthermore, the system\u2019s performance is strongly influenced by the inertia of the turbine and the generator rated power. These results confirmed the suitability of using the coaxial ducted OWC as a self-sustainable oceanographic sensor-buoy.<\/jats:p>","DOI":"10.1115\/omae2015-41975","type":"proceedings-article","created":{"date-parts":[[2015,10,22]],"date-time":"2015-10-22T06:44:12Z","timestamp":1445496252000},"update-policy":"https:\/\/doi.org\/10.1115\/crossmarkpolicy-asme","source":"Crossref","is-referenced-by-count":2,"title":["Performance Assessment of a Floating Coaxial Ducted OWC Wave Energy Converter for Oceanographic Purposes"],"prefix":"10.1115","author":[{"given":"Juan C.
