“…The results shown in this paper present a more comprehensive view in comparison with the ones presented in Vecchia et al (2015Vecchia et al ( , 2016. These references use only the seasonal means of the wave parameters to perform the simulations and represent the preliminary studies of the proposed design of the OWC device.…”

“…When applying Equations 21 and 23 in the Bernoulli equation, it is possible to determine the velocity of the air in section 3 of the tube and, consequently, the kinetic power of the air. More details about this point can be found in Fox, McDonald and Pritchard (1985) and Vecchia et al (2015).…”

This work aims to focus on proposals that could stimulate the development of small scale integrated devices for the global challenge to provide electric energy from renewable alternative resources without major interventions. It presents an evaluation of a small-scale wave energy extraction system that can be installed in marine near shore structures, such as fishing piers. The system is characterized by a small oscillating-water-column (OWC) converter composed by tubes tied to the pillars of the structure. A mathematical model of the OWC device was developed. The model relies on two main components. The first uses linear wave theory to describe the water level variation inside the tube as a result of a wave passing by. The second considers the air flux converted to mechanical torque using Wells turbine equations. The simulations were carried out for different water depths and wave parameters, to evaluate the ratio between the input and output energy throughout the year. For the case study presented in this paper, the performance would be better as long as the device is placed in a position where the waves are less influenced by the bottom friction, but it still has the necessary increment of the wave height.
