Power absorption and flow-field characteristics analysis for oscillating coaxial twin-buoy wave energy converter by using CFD
Provisionally accepted- Jiangsu University of Science and Technology, Zhenjiang, China
This paper presents a simulation study on a twin-buoy wave energy converter (WEC) using a threedimensional numerical wave pool based on the Computational Fluid Dynamics (CFD) method. The objective is to investigate the hydrodynamic performance and energy conversion characteristics of the device. Several factors are examined, including the elasticity coefficient of the anchor chain, the bottom configuration of the floating body, and the power take-off (PTO) damping coefficient. The heave displacement, heave velocity, and heave force of the converter are calculated under specific wave parameters, and the flow field cloud diagram during the heave motion is analyzed. The results indicate that a wave energy converter with a hemispherical floating body exhibits the best kinematic performance. The influence of the mechanical damping coefficient on the energy conversion performance of the device is studied. By appropriately reducing the mechanical damping coefficient, the energy capturing capability of the device can be increased to a certain extent. These findings can serve as a theoretical basis for the application of deep-water wave energy conversion in engineering and the optimization of future WEC designs.
