Results of an experimental study of a counter-rotating turbine operating on a pneumatic wave energy conversion system are presented. The vertical capture chamber of the water column of the system has a down-facing water intake. An electrical generator (d-c) is coupled to the turbine by a ten-gear-ratio drive train. Tests of the pneumatic wave energy conversion system were conducted with the mouth at two depths in order to vary the natural oscillating frequency of the water column. The maximum electrical power output of the system was approximately 90 W in the monochromatic waves. This value corresponds to a 36-percent efficiency based on the incident wave power in a wave crest width equal to the diameter of the capture chamber. The theoretical maximum efficiency of such a system has been shown to be 50 percent by several investigators.

Final System

The wave energy is one of promising resource for generating electricity in this country. A wave energy conversion system was designed and fabricated; the prototype was tested and its performance was analyzed. The invention herein proposed a system operated by wave resource. This configuration allows the wave resource working to generate electricity. Wave power device operated by the movement of floaters with varying speed connected to the mechanical racks. These mechanical racks move gears and pulleys, which giving forces to the pulley’s belts to rotate. This pulley’s belts connected to the electric generator that produces the electricity. The final system was tested in the coastal area near to Universiti Malaysia Terengganu (UMT) campus. The measurement results clearly show that the available wave resource could be harness into useful work for electric power generation.
