Power from a single wave-energy absorber

Abstract

Wave energy technologies have been around for decades. But for a variety of reasons, including rising oil prices, technological advancements and the sheer grit of a handful of pioneer developers, it has made a huge splash since 2005. This paper presented the result of power absorbed by a single wave-energy absorber. The result showed that maximum mean power was quadratic with exciting force, and more damping coefficient was, the less maximum mean power it became. It was shown that maximum mean power was quadratic with velocity of the body, and the more damping coefficient was, the more maximum mean power it became. It was presented that maximum absorbed power for cylinder oscillating about an axis of symmetry was equal to maximum absorbed power for isolated symmetric bodies and half of the amount of two maximum absorbed power of “cylinder which completely spans the wave-tank and cylinder with cross section”. It was illustrated that graph yielded parabola curve when plotted between maximum absorbed power and cylinder which completely spans the wave-tank, cylinder with cross section and cylinder oscillating about an axis of symmetry, Isolated symmetric bodies. It was depicted that maximum absorbed power is increased when depths of the wave-trains increased both cylinder which completely spans the wave-tank, cylinder with cross section and cylinder oscillating about an axis of symmetry, isolated symmetric bodies. It was finally showed that maximum absorbed power decreased when frequency of the wave-trains increased.
