Airfoil Blender for Blade Optimizations
An airfoil database was developed in the present work. The database includes a multivariate, unstructured grid, Radial Basis Function (RBF), optimization-compatible interpolator for airfoil aerodynamic coefficients. The database was designed to aid complex blade design optimizations carried out in a novel optimization framework, HAWTOpt2, being ...

ABSTRACT Wind tunnel experiments are a key element of fluid mechanics education, enabling students to connect theoretical knowledge with practical observations. Despite their pedagogical value, traditional wind tunnel laboratories often lack outcome orientation, rely on prescriptive procedures, and provide limited opportunities for conceptual ...

Numerical optimization for high efficiency, low noise airfoils [PDF]
One key element in the aerodynamic design of wind turbines is the use of specially tailored airfoils to increase the ratio of energy c apture to the loading and thereby to reduce cost of energy. At the same time, noise reduction i s becoming more and more important.

Parametric research and aerodynamic performance analysis of wind turbine airfoil with added flap
A self-popped up flap is added to the airfoil (S809) suction surface to improve aerodynamic performance under large angle of attack (AOA) inspired by the slightly popped up feathers on the trailing edge of a bird’s wing. The response surface methodology (

Wind Turbine Blade Crack Detection and Assessment in Images Using Machine Learning
ABSTRACT As the wind energy industry matures, inspection of wind turbine blades (WTBs) is shifting from a manual process involving rope access and grading of damage, towards unmanned aerial vehicle (UAV) photography and artificial intelligence‐aided processing of data.

Wind Turbine Control for Spatially Varying Turbulence
ABSTRACT This study investigates the influence of inflow turbulence generation simulation methods and blade pitch control strategies on the performance and blade structure loading of a large offshore wind turbine. Two inflow representations were considered: synthetic Kaimal turbulence generated in accordance with IEC design standards and large‐eddy ...

Coastal Marine Carbon and Air‐Sea Fluxes Quantified From pH Sensors on an Extended AUV Deployment
Abstract For the first time, the Autosub Long Range (ALR) completed a fully autonomous, long‐distance (2,000 km) scientific mission, delivering new insight into coastal carbonate dynamics and air‐sea CO2 ${\text{CO}}_{2}$ fluxes. Equipped with a suite of oceanographic sensors, including a Lab‐on‐Chip (LOC) pH sensor and a Sea‐Bird SeaFET pH sensor, the

Self-noise produced by an airfoil with nonflat plate trailing-edge serrations [PDF]
This paper represents the results of an experimental study aimed at reducing the airfoil self-noise by the trailing edge serration of four different sawtooth geometries (defined in the serration angle and length).
