地球上化石資源長期為人類所開發利用,受限於儲存量有被耗竭之危機,及嚴重汙染､破壞環境諸因素,近世來能源利用之覺醒,啟動再生能源之開發已迫在眉捷;波能發電技術此再生能源之開發可顯示其優勢,採固定式防波堤發電機,既可用來保護海岸､減少海岸被侵蝕,又可做為船舶停靠碼頭,世界各國都積極研究OWC安裝於海岸最適地點,取得最佳效率化｡
台灣位於海洋最佳位置,並為世界專家評為再生綠能產業最有前途的地方,但台灣政府以追求GDP而大量使用石化原料,缺乏長遠視野,已造成環境嚴重破壞,而再生波能僅佔產業之微量,殊為可惜,有鑒於此,本文以使用實驗方式來介紹OWC氣室內的現象,以及研究外型設計之優化以取得最大波能,針對不同背板角度､導板､入口開口寬度進行分析波能的取得,由三種實驗模型中,發現改變OWC背板角度所擷取的能源最為明顯,實驗探討冀能為台灣再生能源產業提一最佳方案｡

Renewable green energy is becoming increasingly important due to the expected limit of fossil energy resources and to reduce pollution. Wave energy generation technology has been significantly developed in recent years among numerous types of renewable energy. Fixed breakwater, used to protect shorelines, marine structures, moored vessels, marinas and harbors from wave attacks, may be considered as a common site for installing oscillating water column (OWC) for exploited wave energy. Wave energy have been considered by many experts as one of the most promising green energy for Taiwan. However, the amount of wave energy presently generated constitutes a minor percentage of Taiwan’s total energy production. This paper presents experimental results of a laboratory water chamber of OWC, wherein the fundamental parameters of geometrical design are individually investigated and optimized, for maximum wave energy.
The effects of a variety of back plates angle, fence plates and open wide inlets of OWC chamber are analyzed and tested for catching capability of wave energy. Three experimental models are tested to include an evaluation of the effectiveness of back plate, fence plate and open wide inlet. The operation of OWC qualitatively differs from that predicted by linear theory, identify to critical flow characteristic; front wall down-wash in the water column. The surveys were then expanded to offer general arrangement or a planning material for the geometry optimization of the chamber that could potentially achieve the largest average amplification factor of an OWC system. The wave energy in the OWC significantly varies with different back angles. The results demonstrate that this new OWC could provide more efficient wave energies.
