Aerodynamic Characteristics of Airfoils Equipped With Gurney Flaps and Vortex Generators for the Entire Range of Pitch Angles

Wind Energy, Volume 29, Issue 5, May 2026.
ABSTRACT An experimental study of NACA0021 airfoil equipped with vortex generators (VGs) and Gurney flaps (GFs) was conducted to assess the effects of these devices on the aerodynamic airfoil performance, the information that is necessary for studying the self‐starting characteristics of vertical axis wind turbines (VAWTs).

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 ...

Design of HAWT Rotor for Non‐Uniform Inflow Conditions: A Theoretical and Experimental Approach for Shear Flow

Energy Science &Engineering, Volume 14, Issue 4, Page 1935-1951, April 2026.
This paper aims to provide a robust design approach for HAWTs operating in shear flow. This study fills a critical research gap by integrating BEM and vortex theories for blade design in non‐homogeneous inflow conditions. The authors of the paper made an effort to develop and test an experimentally unsophisticated model of a turbine working in shear ...

Quantifying the Effects of Spatial Inhomogeneity in an Autoclave LDPE Reactor Using CFD

Macromolecular Reaction Engineering, Volume 20, Issue 2, April 2026.
A CFD simulation incorporating rigorous polymerization chemistry into a plant‐scale sliding mesh reactor with multiple PID controllers revealed axial flow patterns that segment the reactor into smaller compartments with different properties. More evident differences exist between the mixture within the agitator shaft swept volume and that outside of ...
