  • 0513 Experimental Study on Efficiency Improvement of Fixed Oscillating Water Column Type Wave Energy Converter

抄録

In the optimum design of a fixed oscillating water column (OWC) type wave energy converter, it is necessary to develop a design method which can consider the characteristics of incident wave motion, the motion of the internal free surface affected in the structure such as a partly submerged wall, the fluctuation of air pressure in an air chamber, the rotation of the air turbine. In this paper, the 2-D wave tank tests for the fixed OWC type wave energy converter with an impulse turbine were conducted to obtain the experimental data needed to make this design method. As the results, the effects of the turbine diameter and the air chamber length on the generating efficiency corresponding to product of the primary and secondary conversion efficiencies are clarified.
