The hydrodynamic principles common to many wave power converters are reviewed via two representative systems. The first involves one or more floating bodies, and the second water oscillating in a fixed enclosure. It is shown that the prevailing basis is impedance matching and resonance, for which the typical analysis can be illustrated for a single buoy and for an oscillating water column. We t...
This paper traces the research stages of China's study of wave energy technology, summarizing the findings and deficiencies of each stage from oscillating water column, through onshore oscillating buoy to floating Duck. It also highlights the major innovations in China's new floating Duck device.
determination of uranium in natural water and complex solutions using ion exchange chromatography: a combined procedure using ion exchange chromatography and uv-vis spectrophotometry techniques has been developed to measure uranum in natural water and complex solutions. after conditicing , one hundred milli liters of sample solutions have been passed through an ion exchange column,pachked with ...
Oscillating water column (OWC) devices and oscillating buoys (OBs) are two of the main types wave energy converters (WECs). In this paper a hybrid column-oscillating buoy converter is proposed, which we have named OWCOB. The hinged at outer wall column. As waves propagate through OWCOB, within OWC chamber moves up down, producing air flow to propel turbine. Meanwhile, oscillation OB drives sepa...
The oscillating water column wave energy converter (OWCWEC) is an established device which produces electricity by causing an ocean wave to drive air through a turbine. A system to control the operation can improve the device’s performance. In varying sea conditions, different objectives for control may be appropriate. For example, in some seas the controller might shut off the plant because th...
