Large-scale experiments on the behaviour of a generalised Oscillating Water Column under random waves

On the tuning of a wave-energy driven oscillating-water-column seawater pump to polychromatic waves

Performance of wave-energy devices of the oscillating water column (OWC) type is greatly enhanced when a resonant condition with the forcing waves is maintained. The natural frequency of such systems can in general be tuned to resonate with a given wave forcing frequency. In this paper we address the tuning of an OWC seawater pump to polychromatic waves. We report results of wave tank experimen...

Experimental Assessment of a Fixed On-Shore Oscillating Water Column Device: Case Study on Oman Sea

Ocean wave is one of the renewable energy resources that these days various devices are used to extract its energy. Oscillating Water Column (OWC) installed on the shore is one of the wave energy absorption systems which has received attention due to its simple structure. Investigation of the pneumatic power is of great importance in such systems as the conversion of wave energy to pneumatic en...

Pneumatic Performance of a Non-axisymmetric Floating Oscillating Water Column Wave Energy Conversion Device in Random Waves

A stochastic approach is used to gain a sophisticated understanding of a nonaxisymmetric floating oscillating water column’s response to random waves. A linear, frequencydomain performance model that links the oscillating structure to air-pressure fluctuations with a Wells Turbine in 3-dimensions is used to study the device performance at a northern California deployment location. Both short-te...
