Abstract
Abstract Nowadays the global demand for energy is growing rapidly in China, which will be the world’s largest country of energy consumption, it is thus highly urgent to conduct the research and development of efficient renewable wave energy equipment, e.g. wave energy converter (WEC). So, this paper aims to numerically develop a new WEC suitable for wave conditions in Zhoushan sea area. The specific research contents include the following aspects: (1) theoretic design by using the floating pendulum to capture the wave energy; (2) Computational Fluid Dynamics (CFD) simulation which is based on 3-Dimensional unsteady Reynolds Average Navier-Storkes (RANS) equations to analyze the hydrodynamic performance of floating pendulor capturing wave energy. The initial design has been optimized to find the parameters of swing device floating in different output loads of energy capture, and to recognize the conditions of the device for subsequent energy conversion system design.
