A method for estimating the extent of denitrification of Arctic polar vortex air from tracer-tracer scatter plots [PDF]
, 2002 A method for estimating the extent of denitrification of Arctic polar vortex air is proposed. Previous estimates of denitrification using tracer-tracer scatter plots have not allowed for mixing-induced changes in tracer-tracer relationships in a ...

Vortex Breakdown in a Swirling Jet with Axial Forcing [PDF]
, 2007 A swirling jet has been generated in water by passing the fluid through a rotating honeycomb and discharging it into a water tank. Experiments were conducted at 3000 < Re < 7000 and 1.15 < S < 1.5.

Internal Frame Dragging and a Global Analog of the Aharonov-Bohm Effect [PDF]
, 1991 It is shown that the breakdown of a {\it global} symmetry group to a discrete subgroup can lead to analogues of the Aharonov-Bohm effect. At sufficiently low momentum, the cross-section for scattering of a particle with nontrivial $\Z_2$ charge off a ...

Simulation of flow around a slender body at high angles of attack
MATEC Web of Conferences, 2017 LES of the flow around an ogive-cylinder body at high angles of attack were carried out to investigate the possibility of the development of asymmetric wake-vortex without the introduction of artificial perturbations. The study investigated the effect of

Aerospace, 2023 Laminar-to-turbulent transition in a swept flat-plate boundary layer is caused by the breakdown of the crossflow vortex via high-frequency secondary instability and is promoted by the wall-surface roughness and the freestream turbulence (FST).

Nonlocal theory of area-varying waves on axisymmetric vortex tubes [PDF]
, 1994 Area and axial flow variations on rectilinear vortex tubes are considered. The state of the flow is characterized by two dependent variables, a core area, and an azimuthal circulation per unit length, which vary in time and in distance along the length ...
