Physical Modeling of Structure and Dynamics of Concentrated, Tornado-like Vortices (A Review)
AerospacePhysical modeling is essential for developing the theory of concentrated, tornado-like vortices. Physical modeling data are crucial for interpreting real tornado field measurements and mathematical modeling data.

Acoustic and Thermoacoustic Jet Propulsion [PDF]
Journal of Applied Fluid Mechanics, 2023 This manuscript bridges the fields of jet propulsion, synthetic jets and thermoacoustic engines. We introduce the case that synthetic jets in air can be considered a consistent approach for propulsion systems. To date, studies on synthetic jet propulsion

Switching and instabilities of optical vortices in nonlinear dual-core photonic crystal fibre couplers [PDF]
Journal of the European Optical Society-Rapid Publications, 2006 We study switching of an optical vortex launched into one core of a dual-core waveguide coupler in a photonic crystal fibre with self-focusing nonlinearity.

Computational Study on the Effect of Vane Design in Enhancing the Mixing of Subsonic Jet and Sonic Jet [PDF]
Journal of Applied Fluid Mechanics, 2023 The purpose of this study is to numerically analyze the effect of vortex generators that are shaped like vanes in enhancing the mixing of subsonic and sonic jet and to determine the best design which yields maximum reduction in jet potential core length ...

Casimir Force between Two Vortices in a Turbulent Bose–Einstein Condensate
Atoms, 2020 We consider the Casimir force between two vortices due to the presence of density fluctuations induced by turbulent modes in a Bose–Einstein condensate. We discuss the cases of unbounded and finite condensates.
