| 英文摘要 | The reciprocating motion of waves poses significant challenges in improving overall conversion efficiency. In this study, the concept of a single floating oscillating water column (OWC) with two chambers separated by a buoyancy module was proposed based on the diffraction and focusing characteristics of wave propagation. Experimental investigations were conducted in a wave flume and tank to validate this concept. The results of small-scale model tests in a narrow wave flume revealed a peak Capture Width Ratio (CWR) of 197.8% under regular wave and 84.3% under irregular waves. In large-scale model tests conducted in a wide wave tank, the peak CWR reached 252.6%, accompanied by a peak wave-to-battery efficiency of 77.1% in regular wave cases. The results suggest that this technology offers simplicity, a shallow draft, low material cost, and high conversion efficiency. Research results provide the effective reference for OWC operation at open sea. Further research is warranted to address the three major challenges wave energy technologies face: high cost, poor reliability, and low conversion efficiency. |
