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).

Lubricant Jet Flow Phenomena in Spur and Helical Gears with Modified Addendums; for Radially Directed Individual Jets [PDF]

This paper develops the mathematical relations for the Virtual Kinetic Model as an improvement over the vectorial model developed earlier. The model solution described provides the most energy efficient means of cooling gears, i.e., it requires the least

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.

Modeling the Detectability of Energetic Heliospheric Ions at Pluto During the New Horizons Flyby

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract We investigate the detectability of heliospheric helium ions at energies up to 100 keV by the New Horizons (NH) spacecraft during its flyby through Pluto's induced magnetosphere. The Pluto Energetic Particle Spectrometer Science Investigation energetic ion detector observed a reduction in their flux by an order of magnitude as the spacecraft ...

Magnetopause Boundary Layers in Low Mach CME‐Driven Storm Environment

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Magnetopause boundary layers (BLs) play an important role mediating plasma and energy exchange between the solar wind/magnetosheath and Earth's magnetosphere. Energy exchange across the magnetopause is enhanced during storms, yet little work has been done investigating BLs during storms.

Dynamically‐Informed Extreme Event Attribution Using Circulation Imprints

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract We present a novel extreme event attribution approach, isolating dynamical from other contributions to changing extreme event probability. Event‐specific, multivariate circulation imprints are linked to impact‐relevant hazard indices in a flexible framework which we demonstrate for three recent high‐impact extreme events: the 2025 Los Angeles ...
