Assimilation of Velocity Data for Tidal Hydrodynamics Model Calibration

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 8, August 2026.
Abstract Assessing tidal stream energy resource typically involves the application of numerical models calibrated against sparse Acoustic Doppler Current Profiler (ADCP) data. This introduces significant challenges in energetic sites which are prone to significant spatiotemporal variations, like the Pentland Firth, Scotland, which is home to the world ...

Multi‐Strategy Synergy‐Based Differential Evolution for Large Wind Farm Layout Optimization

CAAI Transactions on Intelligence Technology, Volume 11, Issue 4, Page 994-1018, August 2026.
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 (

Corrosion and Degradation of Materials in Marine Environments: Implications for Coastal and Offshore Infrastructure

Engineering Reports, Volume 8, Issue 7, July 2026.
This study presents a failure‐oriented analysis of corrosion in marine infrastructure, linking degradation mechanisms to crack initiation, fatigue propagation, and structural failure. A unified framework is proposed to connect environmental exposure, material degradation, and reliability, supporting failure prediction, inspection planning, and life ...

Guide Vanes for Darrieus Water Turbine in Tidal Current

RE&PQJ
On purpose to enhance the performance of a Darrieus-type water turbine for the power generation using a tidal current, the technique with guide vanes were applied. The guide vanes placed in front of the turbine, were expected to allow the turbine to rotate with higher speed by turning the direction of the current partially.
