Measurement of Wave Power Available for Focusing: Discussion and Recommendations

摘要

The ocean wave energy project at the Central Institute for Industrial Research (CIIR) involves concentration of the wave energy, by means of focusing, prior to the energy conversion. In order to evaluate the usefulness of this concept, the authors needed information about the amount of wave energy that can be collected by means of wave focusing. For that purpose, the authors need data on the directional and frequency distribution of the wave energy. The report considers this problem in some detail. A brief review is given of energy flux concentration by means of focusing and its dependence on wave statistics. The authors then consider the general problem of relating the appropriate wave characteristics to measureable quantities. The rest of the report is devoted to a review of possible measurement methods.
