“…This technique, used to simulate the PTO effect upon the OWC, was previously applied by Refs. [8,18,19] successfully. The advantage of using CFD numerical results for the OWC performance is to take into account viscous losses in the energy transfer made from the waves to the OWC.…”

“…However, if the purpose of the OWC structure is to reduce transmitted waves, vortex-induced energy loss is beneficial to the total energy dissipation and can improve the wave protection performance. To date, most of the studies of OWC focus on the energy extraction (e.g., [23][24][25][26][27][28][29]), and there have only been a few earlier studies touching upon the vorticity characteristics of OWC (e.g., [30][31][32]). Analytical and numerical studies based on potential theory are with certain limitation in dealing with viscous effects, while numerical studies based on viscous flow theory need experimental results for validation.…”

“…Senturk and Ozdamar (2011) analyzed a simplified theoretical model of the Japanese OWC device Kaimei and reported a deviation of up to 30% between the analytical solution and the numerical result for nozzle velocity. Zhang et al (2012) numerically replicated the experiments of Morris-Thomas et al (2007) and reported over prediction of the efficiency due to complex pressure changes in the chamber around resonance. It has to be noted that the use of a nozzle in an experiment is to simulate non-linear external damping and the nozzle width determines the amount of damping on the chamber.…”
