In order to achieve maximum pneumatic power in an Oscillating Water Column (OWC) device, it is crucial for the chamber to operate as close to the resonance condition as possible. This means that the frequency of the incident wave must match the resonant frequency of the converter. This resonant frequency is influenced not only by the dimensions of the OWC chamber but also by the incoming wave direction. In this talk, I will first briefly describe the working mechanism of an OWC device, and then I will explore why the Mutriku OWC Energy Plant in Gipuzkoa (northern Spain) inspired this work. The analytical and numerical methods used to study the effect of chamber geometry, incident wave angle, and wave height are also presented, and their limitations are addressed at the end.
