On the Internal Gas Dynamics and Efficiency of a Vortex Water-Vapor Plasma Generator
(2017-06-17)
Results of experimental investigations of a new-type generator of an arc water plasma, having a high thermal efficiency close to 100%, are presented. This generator represents a system comprising a vortex arc plasma ...
Longitudinal vortex generator applied to heat transfer enhancement of a flat plate solar water heater
(Elsevier B.V., 2019-07-25)
The population growth and industrial development increase the demand for energy and the solar energy conversion is an important alternative to complement the world energy matrix. Flat plate solar collectors are devices ...
Regimes of Near-Wall Vortex Dynamics in Potential Flow Through Gaps
(Physics of Fluids, 2008-01-01)
A two-dimensional problem of the motion of a single vortex near an infinite straight wall with singular gaps is solved both analytically, using a point-vortex approach, and numerically based on the method of contour surgery ...
Vortex Generation and Aeroacoustics in Asymmetric Wakes
(2015-01-01)
High-lift devices in an aircraft are important sound generators. These devices should be studied in order to further reduce overall aircraft noise. The high-lift devices operating at a high angle of attack promote the ...
Vortex dynamics and scalar transport in the wake of a flat-plate controlled by a vibrating trailing-edge flap
(Elsevier, 2020)
We investigate the onset and development of vortical flow disturbances introduced into the wake of a horizontally fixed flat-plate by means of the controlled motion of a trailing edge flap. The vibrating mechanics of the ...
Heat transfer in an oval tube heat exchanger with different kinds of longitudinal vortex generators
(American Society of Thermal and Fluids Engineers, 2017)
A numerical study was performed on a plate fi n and oval tube heat exchanger with diff erent kinds of longitudinal vortex
generators (LVG). The infl uence of LVG on heat transfer and pressure drop is investigated, and ...
Vortex-lattice formation in a spin-orbit coupled rotating spin-1 condensate
(2020-11-06)
We study the vortex-lattice formation in a rotating Rashba spin-orbit (SO) coupled quasi-two-dimensional (quasi-2D) hyper-fine spin-1 spinor Bose-Einstein condensate (BEC) in the x-y plane using a numerical solution of the ...
Phase-separated vortex-lattice in a rotating binary Bose–Einstein condensate
(2019-06-15)
We study circularly-symmetric phase separation of vortex lattices in a rapidly rotating harmonically-trapped quasi-two-dimensional binary Bose–Einstein condensate (BEC) by introducing a weak quartic trap in one of the ...
Vortices and turbulence in trapped atomic condensates
(National Academy of SciencesWashington, DC, 2014-03)
After more than a decade of experiments generating and studying the physics of quantized vortices in atomic gas Bose-Einstein condensates, research is beginning to focus on the roles of vortices in quantum turbulence, as ...
Vortex-lattice in a uniform Bose-Einstein condensate in a box trap
(2019-01-01)
We study numerically the vortex-lattice formation in a rapidly rotating uniform quasi-twodimensional Bose-Einstein condensate (BEC) in a box trap. We consider two types of boxes: square and circle. In a square-shaped 2D ...
