Abstract:
In recent years there has been increased attention towards developing the strategies for harnessing hydrokinetic and wave energy from the ocean. There exists several hydrokinetic energy devices designed to extract energy from the ocean current but few wave energy devices are available. The moored floating cylinder-like structure that has been recently developed in South Korea is one of such devices. We carry out numerical simulation of the three-dimensional interactions of a floating cylinder and incoming waves using the level-set curvilinear immersed boundary method of Kang and Sotiropoulos (2012) to improve the understanding the wave energy extraction mechanisms of that device. The results demonstrate the potential of our numerical model as a powerful engineering tool for predicting complex wave-structure interaction phenomena associated with energy extraction devices.
