Photoelectrochemical Charge Excitation Enhancement by Triboelectric Nanogenerator for High‐Efficiency Self‐Powered Anticorrosion

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 3, May 2026.
The synergy of solar and mechanical energy enables a self‐powered photoelectrochemical cathodic protection system, which enhances carrier separation for efficient and sustainable anticorrosion. Harnessing the synergy of solar and mechanical energy presents a potential strategy for high‐efficiency photoelectrochemical cathodic protection.

High‐speed infrared video analysis of sonations in the scissor‐tailed nightjar Hydropsalis torquata

Journal of Avian Biology, Volume 2026, Issue 3, May 2026.
Many species of nightjar reportedly produce short, impulsive wing sounds during courtship, but the kinematics and physical mechanisms of sound production remain speculative. Using synchronized infrared high‐speed video and audio recordings we describe the mechanism of sound production of a sonation in the nocturnal family Caprimulgidae; the wing ...

Feasibility Study of implementing Wake Steering in Floating Wind Farms: Power Gain, Load Estimation and Economic Analysis

Wind Energy, Volume 29, Issue 5, May 2026.
ABSTRACT This paper presents an overview of the CONFLOWS project, a collaborative effort between DNV, Marine Power Systems (MPS) and Durham University. The project investigates the effects of wake steering from aerodynamic, structural and economic modelling perspectives, aiming to provide a comprehensive understanding of its impact on performance and ...

Flow-plate interactions: Well-posedness and long-time behavior [PDF]

, 2013
We consider flow-structure interactions modeled by a modified wave equation coupled at an interface with equations of nonlinear elasticity. Both subsonic and supersonic flow velocities are treated with Neumann type flow conditions, and a novel treatment ...

An Engineering Model for Static Yawed Wind Turbines Based on Actuator Line Simulations and Symbolic Regression

Wind Energy, Volume 29, Issue 5, May 2026.
ABSTRACT Yaw engineering models are commonly used as add‐ons to the industrial blade element momentum (BEM) framework to improve load and power predictions by accounting for the skewed wake effect. However, existing yaw engineering models show noticeable limitations in accurately predicting the induced velocity distribution across the blade span.

Wind Turbine Model Validation Is Improved by High‐Resolution, Measurement‐Derived Inflows

Wind Energy, Volume 29, Issue 5, May 2026.
ABSTRACT There is an increased need for accurate validation of turbine models used by original equipment manufacturers to fine‐tune prototypes and predict power performance and maintenance needs while avoiding costly warranty payouts. Perhaps the most substantial source of uncertainty in typical wind turbine model validation procedures is the use of ...

An Explicit, Compact, and Rotation‐Agnostic Formulation for Equivalent Nodal Loads for Point‐Loaded Beams

International Journal for Numerical Methods in Engineering, Volume 127, Issue 7, 15 April 2026.
ABSTRACT In time‐marching dynamical simulations, treatment of contact forces in deformable bodies represented by finite element meshes requires a compromise between simulation fidelity and computational costs. External forces directly evaluated at the mesh nodes offer better computational performance at the cost of modelling fidelity.

Aeroelastic Characteristics of Rotor Blades of Last Stage of a Powerful Steam Turbine

Journal of Mechanical Engineering, 2023
Blades of powerful steam turbines are subjected to significant unsteady loads, which, in some cases, can lead to the appearance of self-excited oscillations or auto-oscillations.
