A Comprehensive Review of AI‐Powered Energy Systems

Energy Science &Engineering, EarlyView.
The role of Artificial Intelligence (AI) in developing next‐generation energy systems is getting more day by day. Therefore, incorporating AI enables real‐time decision‐making and advanced grid management, which are essential for optimizing the use of intermittent renewable sources like wind and solar power.

Role of Fiber Sizing in Interfacial Relaxation, Water Uptake and Fatigue Properties of Acrylic‐Matrix Composites

Polymer Composites, EarlyView.
Characterisation of glass fibre reinforced acrylic with acrylic‐tailored or multi‐compatible sizing agents. ABSTRACT Fiber‐reinforced infusible acrylic monomer resins are of interest as recyclable alternatives to epoxy and other thermoset resin composites, but the novelty of these resins causes published studies on acrylic‐matrix composites to often ...

DFIG versus PMSG for marine current turbine applications [PDF]

, 2012
Emerging technologies for marine current turbine are mainly relevant to works that have been carried out on wind turbines and ship propellers. It is then obvious that many electric generator topologies could be used for marine current turbines. As in the

CFD Simulations of the Effects of Wave and Current on Power Performance of a Horizontal Axis Tidal Stream Turbine

Journal of Marine Science and Engineering, 2023
To ensure the long-term reliability of tidal stream turbines, waves and currents must be considered during the design phase. In this paper, a three-bladed horizontal axis turbine with a diameter of 0.9 m was used as the baseline model.

Impact of structural flexibility on loads on tidal current turbines [PDF]

International Journal of Marine Energy, 2016
In the development of tidal current turbines there are two common approaches regarding the required level of detail for load simulations. Those two are either to simulate the pressure field in detail with computational fluid dynamics (CFD) and assume a rigid geometry or to use a high fidelity structural model and simulate the hydrodynamic blade loads ...

Riverine Migration Success of Salmonid Smolts Following Their Entrainment in a Hydropower Off‐Channel Diversion in an Upland River

River Research and Applications, EarlyView.
ABSTRACT Salmonid fishes typically express anadromy. During their juvenile riverine emigration, their downstream movements can be inhibited by hydropower schemes that entrain fish in their intakes. Here, the riverine migration success of smolts of brown trout Salmo trutta (“trout smolt”) and Atlantic salmon Salmo salar smolts (“salmon smolt”) was ...

Design and testing of a contra-rotating tidal current turbine

, 2005
A contra-rotating marine current turbine has a number of attractive features: nearzero reactive torque on the support structure, near-zero swirl in the wake, and high relative inter-rotor rotational speeds.

Efficient Harvesting of Irregular and Low‐Frequency Mechanical Energy via Hybridized Electromagnetic‐Triboelectric Systems

Small, EarlyView.
ABSTRACT The rapid expansion of the Internet of Things (IoT) and wearable electronics necessitates sustainable power sources to replace the limited electrochemical battery. While mechanical energy harvesting offers a promising solution, traditional harvesters face challenges of irregular and low−frequency environmental sources. This review presents the
