Abstract

The purpose of this research is to introduce and investigate an onshore Hybrid Wave Energy Converter (HWEC) including an onshore Oscillating Water Column (OWC) and a Horizontal Floating Cylinder (HFC). The performance of the proposed hybrid wave energy converter is investigated in a numerical tank. Numerical simulation is performed using ANSYS-Fluent software. In this study, waves are generated using the nonlinear second-order stokes theory. Also, the SST k−ω turbulence model and volume of fluid scheme are used for turbulence modeling and interface tracking respectively. The results show that the efficiency of the hybrid wave energy converter is higher than the efficiency of a single oscillating water column and the efficiency of a single horizontal floating cylinder. Moreover, in the present study, the effect of some geometrical parameters of OWC and HFC on the performance of the HWEC are investigated. Finally, some appropriate values for each parameter in each wave period are presented. The results show that the more effective parameters on the performance of the hybrid wave energy converter are the orifice width and the chamber width in the OWC and also the damping coefficient and the cylinder distance from the oscillatory water column in the HFC.
