Symmetry-breaking vortex-lattice of a binary superfluid in a rotating bucket
(2020-02-06)
We study spontaneous-symmetry-broken phase-separated vortex lattice in a weakly interacting uniform rapidly rotating binary Bose superfluid contained in a quasi-two-dimensional circular or square bucket. For the inter-species ...
Heat Transfer Enhancement in a Flat-Plate Solar Water Heater Through Longitudinal Vortex Generator
(2019-08-01)
The solar energy is a renewable source that has a great potential for conversion into thermal energy or for generation of electric power through photovoltaic panels in Brazil. Concerns about environmental impacts and the ...
Heat transfer enhancement in panel type radiators using delta-wing vortex generators
(Elsevier France-editions Scientifiques Medicales Elsevier, 2019-03)
In this paper, a three-dimensional numerical simulation is used to analyze the performance of delta-wing vortex generators for enhancing the heat exchange in panel type radiators, which are widely used in electric power ...
Simulação numérica da interação entre uma nuvem incidente de vórtices e uma aerofólio através do método dos vórtices
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Engenharia MecânicaTecnologia de Materiais; Projetos Mecânicos; Termociências, 2005-09-16)
The study of aerodynamic loading variations has many engineering applications, including helicopter rotor blades, wind turbines and turbo machinery. This work uses a Vortex Method to make a lagrangian description of the a ...
Parametric optimization of a stamped longitudinal vortex generator inside a circular tube of a solar water heater at low Reynolds numbers
(2021-08-01)
Solar Water Heater (SWH) has low efficiency and the performance of this type of device needs to be improved to provide useful and ecological sources of energy. The passive techniques of augmentation heat transfer are an ...
Time resolved nanosecond vortex dynamics in high Tc superconducting films
(Elsevier, 2004-01)
Flux dynamics in a high Tc superconducting thin film is investigated in the ns time scale. The initial metastable state is determined by applying a pulsed magnetic field to a sample previous cooled below the irreversibility ...

Three-dimensional vortex-bright solitons in a spin-orbit-coupled spin-1 condensate
(2018-01-25)
We demonstrate stable and metastable vortex-bright solitons in a three-dimensional spin-orbit-coupled three-component hyperfine spin-1 Bose-Einstein condensate (BEC) using numerical solution and variational approximation ...
Vortex metrology using Fourier analysis techniques: vortex networks correlation fringes.
(OPTICAL SOC AMER, 2012-10-20)
In this work, we introduce an alternative method of analysis in vortex metrology based on the application of the Fourier optics techniques. The first part of the procedure is conducted as is usual in vortex metrology for ...
