The purpose of this paper is to establish a mathematical model of an experimental facility for simulating OWC (oscillating water column) wave energy conversion in a static pond. The system was successfully used for designing a BD series of wave-activated generators for navigation lighted buoys. Performances and dynamic responses of the system both with an orifice and with a symmetrical aerofoil turbine are caculated and analysised. The digital results tally well with the experimental results. Some questions...

The purpose of this paper is to establish a mathematical model of an experimental facility for simulating OWC (oscillating water column) wave energy conversion in a static pond. The system was successfully used for designing a BD series of wave-activated generators for navigation lighted buoys.

The digital results tally well with the experimental results. Some questions in modelling and parameters selection of OWC wave energy conversion are discussed in the paper.

Several wave directional spreading models in common use are reviewed and compared in this paper. Morever, the wave directional spectra measured with the wave gage array and the ENDECO 956 buoys from some sea areas around China are compared with the Mitsuyasu' s model, the Hasselmann' s model and the Donelan' s model, which were obtained from the field observation, and the Wen' s Wave directional spectrum which was derived analytically, according to four parameters, i. e. the directional spreading,the cumulative curve of the spreading,the maximun and the standard deviation of the spreading.The results show that the Donelan' s model conforms to the measured spreading best and the Wen' s model takes the second place. Morever ,the modified Mitsuyasu' s model which was obtained by authors to fit the measured directional spectra by a wave gage array in the Bahai Sea is also in agreement with the field data.
