Study on Longitudinal Collision Risk of Closely Spaced Parallel Runways Paired Approach
Promet (Zagreb)This study asserts that paired aircraft can withstand specific wake turbulence levels and explores the longitudinal collision risk in closely spaced parallel runway approaches. The goal is to enhance the safety margin of the paired approach and allow for

, 1997 We study the effect of a transport current on the vortex-line lattice in isotropic type-II superconductors in the presence of strong thermal fluctuations by means of 'driven-diffusion' Monte Carlo simulations of a discretized London theory with finite ...

Spin-orbit conversion at the sharp focus of a circularly polarized light beam
Компьютерная оптикаIt is known that when tightly focusing a circularly polarized optical vortex, spin-to-orbital angular momentum conversion occurs. It is usually said that the longitudinal component of the spin angular momentum (SAM) vector is transformed into the ...

Vortex boundary-layer interactions [PDF]
The interaction of a turbulent boundary layer (on a flat plate) with a strong artificially-generated longitudinal vortex, which may or may not actually enter the boundary layer, was studied.

Numerical simulation of a longitudinal vortex
, 2019 Longitudinal vortices are common flow phenomena in the flow around aircrafts. They develop wherever sharp corners are encountered, like on wing tips, tail plane or in the cut-out between surfaces. Numerical investigations performed with RANS models about the flow interactions with longitudinal vortices usually show large discrepancies with respect to ...

Direction of energy flows at the focus of cylindrical vortex vector beams
Компьютерная оптикаIn this work, we show analytically using the Richards-Wolf formalism and through the numerical simulation that at the sharp focus of a circularly polarized optical vortex, three energy flows occur: the direct longitudinal, reverse longitudinal, and ...

Collective Oscillations of Vortex Lattices in Rotating Bose-Einstein Condensates
, 2003 The complete low-energy collective-excitation spectrum of vortex lattices is discussed for rotating Bose-Einstein condensates (BEC) by solving the Bogoliubov-de Gennes (BdG) equation, yielding, e.g., the Tkachenko mode recently observed at JILA.
