Surface Characterisation of Kolk-Boils within Tidal Stream Environments Using UAV Imagery
Journal of Marine Science and Engineering, 2021 High-flow tidal stream environments, targeted for tidal turbine installations, exhibit turbulent features, at fine spatio-temporal scales (metres and seconds), created by site-specific topography and bathymetry. Bed-derived turbulent features (kolk-boils)

Lifetime Analysis of IGBT Power Modules in Passively Cooled Tidal Turbine Converters
Energies, 2020 Thermal cycling is one of the major reasons for failure in power electronic converters. For submerged tidal turbine converters investigating this failure mode is critical in improving the reliability, and minimizing the cost of energy from tidal turbines.

An approach to the characterisation of the performance of a tidal stream turbine [PDF]
Renewable Energy, 2017 In order to better manage and maintain deployed Tidal Stream Turbine (TST) devices their response to complicated and severe loading mechanisms must be established. To aid this process the research presented details a methodology for mapping TST operational data, taken under a variety of operating conditions, to a set of model parameters.

Cost modelling and design optimisation of tidal stream turbines [PDF]
, 2021 A newly developed cost model for tidal stream turbines is presented. The model is based on (a) an existing tidal stream turbine cost model, (b) published CapEx data from an operational tidal stream turbine array, and (c) wind turbine cost data. The new cost model is utilized to establish cost-effective tidal stream turbine design, with the aim of ...

Tidal stream turbine power capping in a head-driven tidal channel [PDF]
Renewable Energy, 2019 Abstract An array of ten 1 MW turbines, with a one diameter inter-turbine spacing, is simulated in a hypothetical tidal channel using the depth-averaged flow solver TELEMAC-2D. It has been shown for idealised turbines that mean power extraction from tidal channels can be enhanced by tuning turbine resistance for a given channel.

Multi‐Strategy Synergy‐Based Differential Evolution for Large Wind Farm Layout Optimization
CAAI Transactions on Intelligence Technology, EarlyView.ABSTRACT Exploring clean energy alternatives to fossil fuels has become a major research focus worldwide. Wind energy is regarded as one of the most promising renewable energy sources due to its clean and sustainable nature. However, wake interactions among turbines significantly reduce power conversion efficiency, making wind farm layout optimization (
