Study on the influence of topography on wind shear numerical simulations based on WRF–CALMET [PDF]

Geoscientific Instrumentation, Methods and Data Systems
This study focuses on the critical issue of low-altitude wind shear, which is vital for aircraft safety during takeoff and landing. Using the WRF–CALMET model, we assess the impact of topography on low-level wind shear at Zhongchuan Airport.

STRONG WIND AND VERTICAL WIND SHEAR ABOVE 30 km

, 1969
Abstract : Strong wind and vertical wind shear must be considered for design and operation of vehicles that will either operate in or penetrate the upper stratosphere and mesosphere. Global extremes of these atmosphere parameters are estimated in this report for altitudes above 30 km. For the Northern Hemisphere estimated 90, 95, and 99% winds, related

Design and Analysis of Compression–Torsion Coupling Metamaterials Using the Golden Section Method

Advanced Engineering Materials, EarlyView.
A novel compression–torsion metamaterial is engineered using inclined rods and symmetry breaking. To optimize its torsional performance, the golden section method is employed. The mechanical response of the metamaterial is validated through both numerical analysis and experimental validation.

Non‐Monotonic Convective Response to Vertical Wind Shear: A Closer Look From Cloud Resolving Model Simulations

Journal of Advances in Modeling Earth Systems
Using a three‐dimensional cloud‐resolving model, a systematic exploration is undertaken of the response of a radiative‐convective equilibrium state to imposed vertical wind shear of varying magnitude.

Seasonality of Vertical Wind Shear in the Northwestern North Atlantic

Wind Energy
ABSTRACT Compared to onshore, offshore wind offers a more consistent resource, potential close proximity to load centers, and greater distance from people's view sheds. Much of our understanding of the wind resources in the western north Atlantic derives from remote sensing and scattered measurements.

Influence of Scan Strategies in Electron Beam Powder Bed Fusion on Solidification, Microstructure, and High‐Temperature Compressive Properties of γ′‐Strengthened Inconel 738LC

Advanced Engineering Materials, EarlyView.
Experiments and thermophysical simulations were conducted to investigate the electron beam powder bed fusion electron beam (PBF‐EB/M) process for the γ′‐strengthened nickel‐based superalloy Inconel 738LC. The results demonstrate the impact of process‐induced microstructural variations on high‐temperature mechanical behavior, providing a basis for ...

Additive Manufacturing of Alumina‐Reinforced Elastomers

Advanced Engineering Materials, EarlyView.
Vat‐photopolymerized elastomers reinforced with platelet‐shaped alumina exhibited preferential orientation, reduced porosity, and significantly enhanced mechanical performance. A 3 wt% platelet loading increased tensile strength from 12.4 to 45.7 MPa, highlighting the critical role of filler morphology in elastomeric VPP composites.
