Optimization of Power Absorption From Sea WavesSource: Journal of Energy Resources Technology:;1979:;volume( 101 ):;issue: 002::page 145DOI: 10.1115/1.3446905Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This article presents a generalized procedure for selecting rationally the design parameters of a simple wave power absorption system. The system utilizes a tethered-symmetrical float which rides the sea waves and transmits the wave energy to a viscously damped load. The optimum load levels corresponding to the different sea states are determined, for several float geometries, in order to maximize the overall efficiency of wave-power conversion. The optimum float dimensions are constrained to guarantee that the float will not leave the wave crest during its upward travel or sink below the wave trough as it goes downward. These constraints, if overlooked, as has been the case so far in the literature, result not only in improper functioning of the system but also in values of the conversion efficiency higher than reality. The developed procedure predicts also, for different float configurations, the limits that, if satisfied, can guarantee that the system would operate at its maximum possible efficiency irrespective of the sea wave conditions. Therefore, the material presented in the study can be extremely useful in designing efficient wave power absorbers which would help in capturing the vast amount of the renewable and nonpolluting sea wave energy.
