Special Issue Information

Dear Colleagues,

Wave energy conversion is fast approaching commercialisation. Lessons learnt, global warming, the interest of oil and gas sector, and the need to diversify the mix of offshore renewables are driving the latest momentum in wave energy innovation.

However, operating near the water’s surface exposes wave energy devices to slamming loads, surface piercing, and other marine challenges, such as biofouling and solar radiation, which can increase the difficulty of maintenance.

To avoid set downs due to mechanical failures and loss of interest among investors, several factors, such as structural reliability and performance, need to be continuously improved.

To achieve this aim, it is necessary to develop novel tools and technologies that contribute to the design and performance of wave energy converters, and in the short and long term, we must deliver a reduction in the cost of wave energy.

This Special Issue will showcase cutting-edge research on conversion mechanisms, methodologies, control algorithms, modelling tools, experimental prototypes, and other approaches to enhance the performance and structural integrity of wave energy converters.

Topics of interest include, but are not limited to, the following subjects:

  • Novel conversion concepts;
  • Direct wave energy conversion;
  • Experimental approaches;
  • Modelling and analytical methods;
  • Hydrodynamics;
  • Structural integrity;
  • Smart materials;
  • Control algorithms;
  • Wave energy economics.

Hydrodynamic tools reveal information as to the behaviour of a device in the presence of waves but provide little information on how to improve or optimise the device. With no recent work on the transfer of power (energy flux) from a wave field through the body surface of a wave energy converter (WEC), we introduce the energy flux method to map the flow of power. The method is used to develop an open-source tool to visualise the energy flux density on a WEC body surface. This energy flux surface can also be used to compute the total power capture by integrating over the surface. We apply the tool to three WEC classes: a heaving cylinder, a twin-hulled hinged barge, and pitching surge devices. Using the flux surfaces, we investigate power efficiency in terms of power absorbed to power radiated. We visualise the hydrodynamic consequence of sub-optimal damping. Then, for two pitching surge devices with similar resonant peaks, we reveal why one device has a reduced power performance in a wave spectrum compared to the other. The results show the effectiveness of the energy flux method to predict power capture compared to motion-based methods and highlight the importance of assessing the flux of energy in WECs subjected to different damping strategies. Importantly, the tool can be adopted for a wide range of applications, from geometry optimisation and hydrodynamic efficiency assessment to structural design. Full article
