In the field of wind energy, electrical generator solutions have converged on a small number of technologies for specific technical and economic reasons. This paper investigates whether a similar rationale exists within the field of oscillating water column, wave energy converters. The suitability or otherwise of the various generator options in the(More)
Power fluctuations generated by most oscillating wave energy converters without significant amounts of energy storage may have a negative impact on the power quality of the local grid to which they are connected. Assessing this impact on the local network of a potential test site is hence an important step in the selection process of a suitable deployment(More)
Significant electrical power fluctuations in the range of seconds may be generated by most oscillating wave energy converters without significant amounts of energy storage capacity. Because of these fluctuations, a wave farm may have a negative impact on the power quality of the local grid to which it is connected. Hence, the impact of these devices on both(More)
The wave spectral density function, more commonly known as the wave spectrum, has seen widespread use as a tool to measure the wave energy resource at possible sites for the deployment of Wave Energy Converters (WECs). The wave spectrum provides a useful means to calculate summary statistics such as significant wave height and average period from measured(More)
This paper presents a fundamental investigation on optimizing the power takeoff (PTO) for maximizing wave energy conversion of the wave-activated bodies (WABs) wave energy converters. In this research, two relative heave motions are taken for capture power, and a linear PTO is considered in the primary analysis. For such a linear dynamic system, the(More)

The development of wave and tidal energy power generation technology is moving steadily towards pre-commercial status. The multitude of widely differing power capture technologies means that it is a difficult industry to analyse in terms of a common approach to optimal generator selection or design. This paper examines some of the overarching requirements(More)
The mam objective of this research was to understand the fate of naphthalene and nalkylnaphthalenes during diesel combustion, and an evaluation of their sources in diesel exhaust emissions. This was achieved by the use of a procedure which employed a [Cjradiolabelled PAH technique and a diesel enriched fuel technique (DEFT). The combustion of diesel fuel(More)
