Meteorological Applications, Volume 33, Issue 2, March/April 2026.This paper proposes an innovative framework for deterministic and probabilistic wind nowcasting consisting of various machine learning methods. The reliable short‐term wind predictions drive the Wake Vortex Warning System for Vertiports (WVWS‐V), which may enable safe air‐taxi operations at major airports. ABSTRACT Accurate wind prediction is essential

Wind Tunnel Testing on Crosswind Aerodynamic Forces Acting on Railway Vehicles
Journal of Fluid Science and Technology, 2010 This study is devoted to measure the aerodynamic forces acting on two railway trains, one of which is a high-speed train at 300km/h maximum operation speed, and the other is a conventional train at the operating speed 100km/h. The three-dimensional train

X‐ray computed tomography study of terrestrial analog cores in preparation for Mars sample return
Meteoritics &Planetary Science, Volume 61, Issue 3, Page 405-426, March 2026.Abstract Mars Sample Return (MSR) is expected to transform planetary science by providing unprecedented access to pristine Martian material. Initial characterization in the sample receiving facility (SRF) will rely on nondestructive techniques such as X‐ray computed tomography (XCT) to document the condition, distribution, and internal features of ...

Aerodynamic force and moment measurement for crosswind stability assessment in a compact wind tunnel
Mechanical Engineering Journal, 2017 Rolling stock is sensitive to crosswind because of its large side area, so crosswind stability must be assessed when rolling stock is developed. In the European Union, aerodynamic force and moment under crosswind need to be measured in a wind tunnel ...

Numerical Investigation on Flapping Aerodynamic Performance of Dragonfly Wings in Crosswind
International Journal of Aerospace Engineering, 2020 Numerical simulations are performed to investigate the influence of crosswind on the aerodynamic characteristics of rigid dragonfly-like flapping wings through the solution of the three-dimensional unsteady Navier-Stokes equations. The aerodynamic forces,

Applications in Energy and Combustion ScienceFlares are critical for the safe destruction of waste gases and must operate effectively over a broad range of conditions. Even at low gas flow rates, the flames created by flares are highly turbulent and exhibit significant transient behavior, yet few ...
