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).

Modeling, Validation, and Control of the IEA‐15 MW Reference Wind Turbine and VolturnUS‐S Platform

Wind Energy, Volume 29, Issue 5, May 2026.
ABSTRACT This paper presents the acausal modeling, validation, and control of floating offshore wind turbines (FOWTs). The model simulates the IEA‐15 MW reference turbine and the semi‐submersible VolturnUS‐S platform utilizing a Control‐oriented, Reconfigurable, and Acausal Floating Turbine Simulator (CRAFTS), which integrates the key coupled aero ...

Angular Momentum Balance of Superrotation in Venus's Middle and Upper Atmosphere Simulated by AFES‐Venus

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Based on simulations of the Venusian atmosphere using the AFES‐Venus GCM, we investigated the angular momentum (AM) balance that maintains the atmospheric superrotation (SR) at 35–90 km altitudes. In and above the cloud layer, the Eulerian‐mean meridional circulation consists of Hadley‐like cells at low latitudes and Ferrel‐like cells at ...

Highly Trained Female Runners Show Greater Durability and Physiological Resilience Than Performance‐Matched Male Counterparts

Scandinavian Journal of Medicine &Science in Sports, Volume 36, Issue 5, May 2026.
ABSTRACT Endurance performance determinants are typically assessed under fresh conditions, although physiological and mechanical characteristics deteriorate during prolonged exercise, a phenomenon recently termed durability or resilience. However, it is unclear whether durability and mechanisms underpinning it differ between sexes.

Evaluation of Porous Media Properties for the Performance of Sulfur‐Depolarized Electrolysis

ChemSusChem, Volume 19, Issue 8, 28 April 2026.
Sulfur‐depolarized electrolysis (SDE) enables low‐voltage hydrogen production while converting SO2 into H2SO4. This work identifies asymmetric gas diffusion layer (GDL) designs as the key to stable operation, providing the first clear design guidelines for SDE‐tailored GDLs and lay the groundwork for the rational development of next‐generation ...
