Transonic Buffet Suppression by Airfoil Optimization
The main buffet suppression techniques of aircrafts include active and passive flow control, aiming to reduce the impact of the fluctuating loads on the airfoil. These techniques are remedies after the airfoil design. The buffet suppression is not always

Giant Orbital Rashba–Edelstein Effect in Crystalline Cu2O/Cu Heterostructures
An enhanced orbital Rashba–Edelstein effect is demonstrated in a crystalline Cu2O/Cu heterostructure, compared to naturally oxidized CuOx structures, highlighting the critical role of crystallinity and interface control in orbital torque generation. The resulting spin torque conductivity exceeds that of Pt, indicating the potential of orbital torque ...

On Aerodynamic Roll Damping [Elektronisk resurs]
In this paper an approach for estimating aerodynamic roll damping is formulated. The approach utilizes wind tunnel tests and the concept of effective levers to relate roll induced apparent wind to a damping moment. Evaluation of the approach on a typical

Tailoring Phonon‐Driven Responses in α‐MoO3 through Isotopic Enrichment
ABSTRACT The implementation of polaritonic materials into nanoscale devices requires selective tuning of parameters to realize desired spectral or thermal responses. One robust material, α‐MoO3, an orthorhombic crystal boasting three distinct phonon dispersions, provides three polaritonic dispersions of hyperbolic phonon polaritons (HPhPs) across the ...

A Survey of Interlayer Interaction Models for Graphene and Other 2D Materials
Van der Waals interactions arising from electronic polarization at atomically close interfaces generate corrugated interlayer energy landscapes that govern normal and tangential tractions. This review presents an overview of quantum, atomistic, analytical, and continuum modeling approaches, highlighting their roles across length scales in capturing ...

AERODYNAMIC DAMPING UNDER ALONG-WIND OSCILLATIONS
The streamwise oscillation of rectangular sectioned structures are usually caused by the turbulence of the incident flow but also by the resonance effect due to vortex sheddings from the structure in a low turbulent wind.
