A Theoretical Study of the Hydrodynamic Performance of an Asymmetric Fixed-Detached OWC Device

The chamber configuration of an asymmetric, fixed-detached Oscillating Water Column (OWC) device was investigated theoretically to analyze its effects on hydrodynamic performance. Two-dimensional linear wave theory used, and the solutions for associated radiation scattering boundary value problems (BVPs) were derived through matched eigenfunction expansion method (EEM) element (BEM). results efficiency other important properties computed analyzed various cases. Parameters, such as length thickness submergence rear front walls, varied. performance adding a step under OWC reflecting wall in downstream region also investigated. A good agreement between analytical numerical found. Thinner walls low seen increase bandwidth. inclusion slightly reduced frequency at which resonance occurs, when is included, noticeably frequencies due near trapped waves gap rigid vertical wall.
