Continuous and step-wise valve area changes are considered, the second case corresponding to multi-element design. The adequacy of the valve and of its control is assessed through the gain in annual electrical energy and the total number of required valve strokes. The following items are separately analyzed: (i) number of (identical) valve elements; (ii) valve response time; (iii) signal noise level in chamber air-pressure measurements due to large-eddy turbulence; (iv) valve\u2019s control algorithm.<\/jats:p>","DOI":"10.1115\/1.1576815","type":"journal-article","created":{"date-parts":[[2003,7,17]],"date-time":"2003-07-17T22:19:53Z","timestamp":1058480393000},"page":"205-210","update-policy":"https:\/\/doi.org\/10.1115\/crossmarkpolicy-asme","source":"Crossref","is-referenced-by-count":37,"title":["By-Pass Air-Valve Control of an OWC Wave Power Plant"],"prefix":"10.1115","volume":"125","author":[{"given":"A.
