【 摘 要 】

A new wave-generation system, composed of a source and an absorber, is proposed to realize a non-reflective wave field in a laboratory basin as an advanced alternative to conventional methods. Theoretical studies based on the linear potential theory were carried out to investigate the characteristics of wave fields generated by the proposed method. Performance of the new system was compared to that of conventional serpent-type wave-makers. The proposed system was founded to provide a significantly larger effective area for multi-directional waves than does the serpent-type wave makers. Experimental studies using a two-dimensional wave tank were also conducted to verify the performance and practicality of the new system. The results showed that the new devised equipment can produce a nearly non-reflective wave field and can generate waves efficiently even in deep water.
