Special Issue Information

Dear Colleagues,

Wave energy converters (WECs) operate in challenging hydrodynamic environments where irregular seas, strong nonlinearity, and multi-physics coupling govern both energy capture and survivability. Making an accurate prediction of wave–body interactions remains a central bottleneck for efficient design, reliable operation, and cost-effective deployment, particularly as devices move from controlled laboratory conditions toward array-scale and real-sea applications. This Special Issue, “Hydrodynamics of Wave Energy Conversion Systems” (Section: Marine Energy), seeks original research and review articles that advance the numerical modeling and rigorous validation of WEC hydrodynamics. We welcome contributions spanning linear and nonlinear potential flow methods, time-domain solvers, fully nonlinear numerical wave tanks, CFD approaches (e.g., URANS/LES, VOF free-surface capturing), and hybrid multi-fidelity frameworks that balance accuracy and computational efficiency. We additionally encourage submissions that discuss high-quality tank tests and field measurement campaigns, benchmark datasets, scaling and uncertainty analyses, and systematic model–experiment/field comparisons. Topics of interest include, but are not limited to, wave–structure interactions, nonlinear wave effects, WEC arrays, farm interactions, model tests, techno-economic assessments, hybrid modelling, and numerical wave tanks.

The integration of wave energy converters with offshore wind foundations offers a potential route to improving the utilization of offshore renewable energy infrastructure. This study numerically investigates the power-load characteristics of fixed oscillating water column (OWC) chambers intended for potential installation near offshore wind jacket foundations. A preliminary jacket comparison is first used to delimit the scope, after which the main parametric study is performed on isolated OWC chambers so that pneumatic response and local chamber loads can be compared consistently. The simulations are conducted under regular waves with a wave height of H = 0.05 m, a water depth of h = 1.6 m, and wave periods of T = 0.9–1.7 s. Three baseline geometries, namely cylindrical, sandglass-shaped, and bottle-shaped OWCs, are first screened in order to identify the most suitable reference chamber family. The cylindrical chamber is then retained as the reference configuration for subsequent local parameter studies of the frustum-contraction parameter D2 and the front-wall draft d2. The results indicate that the geometric effect is strongly dependent on the incident-wave period. The sandglass-shaped and bottle-shaped chambers can enhance short-period pneumatic power or reduce loads at longer periods, whereas the cylindrical chamber provides a more consistent reference response over the tested range. Under the wave conditions adopted in this study, further analysis reveals that D2 exerts a non-monotonic tuning effect varying with wave period. For the selected frustum-shaped configuration, increasing d2 reduces hydrodynamic loads yet simultaneously weakens pneumatic power output and CWR. Because the air phase is treated as incompressible and the orifice represents an orifice-only damping condition rather than a turbine-controlled PTO system, the reported Pe should be interpreted as a pneumatic/hydrodynamic comparison metric and not as wave-to-wire electrical power. The conclusions are therefore positioned as regular-wave geometry-tuning trends for the present model scale rather than as full coupled jacket-OWC design rules. Full article

Meeting the growing demand for renewable energy production requires tapping into a variety of natural resources. Wave energy, while abundant, remains a challenging and often non-economic field. To address this, the present paper proposes and examines an innovative concept for a wave energy converter (WEC). Alongside survivability capabilities, the novel device enables simultaneous extraction of wave energy in two degrees of freedom and, with additional tuning for a range of sea states, achieves higher efficiency compared to existing technologies. As it does not require a link to the seabed or a wharf for production, the concept is suitable for deep water, hence offering higher potential relative to nearshore WECs. In this study, we present the proposed concept and its engineering simplicity, together with mathematical analysis and preliminary results that evaluate the device’s performance under regular and irregular sea conditions.
