Employing wind tunnel data to evaluate a turbulent spectral model
(Science Publishing Group, 2016)
In this study, spectra obtained from wind tunnel data are compared with a model that describes observed
atmospheric neutral spectra. The investigation points out that there is a good conformity between both spectra for ...

Flow in the wake of wind turbines : turbulence spectral snalysis by wind tunnel tests
(Science Publishing Group, 2016)
The interaction between the incident wind and wind turbines in a wind farm causes mean velocity deficit and increased levels of turbulence in the wake. The turbulent flow is characterized by the superposition of wind turbine ...
Spectral analysis of the turbulent energy cascade and the development of a novel nonlinear subgrid-scale model for large eddy simulation.Análise spectral da cascata de energia turbulenta e desenvolvimento de um novo modelo submalha não linear para simulação das grandes escalas.

Rotating helical turbulence. I. Global evolution and spectral behavior
(American Institute of Physics, 2010-03)
We present results from two 15363 direct numerical simulations of rotating turbulence where both energy and helicity are injected into the flow by an external forcing. The dual cascade of energy and helicity toward smaller ...
Spectral modeling of rotating turbulent flows
(American Institute of Physics, 2010-02)
A subgrid-scale spectral model of rotating turbulent flows is tested against direct numerical simulations (DNSs). The case of Taylor-Green forcing is considered, a configuration that mimics the flow between two counter-rotating ...
Spectral proper orthogonal decomposition and resolvent analysis of near-wall coherent structures in turbulent pipe flows
(2020-01-01)
Direct numerical simulations, performed with a high-order spectral-element method, are used to study coherent structures in turbulent pipe flow at friction Reynolds numbers and. The database was analysed using spectral ...
Helical turbulence prevails over inertial waves in forced rotating flows at high reynolds and low rossby numbers
(American Meteorological Society, 2011-10)
Astudy of spectral laws for helical turbulence in the presence of solid body rotation up to Reynolds numbers Re ~ 1 × 105 and down to Rossby numbers Ro ~ 3 × 10-3 is presented. The forcing function is a fully helical flow ...
Turbulent kinetic energy dissipation rates and eddy diffusivities in the tropical mesosphere using Jicamarca radar data
(Elsevier, 2007-06-06)
The 50-MHz MST radar at Jicamarca Radar Observatory (JRO) can detect atmospheric turbulence on the Bragg scale of 3 m in the daytime mesosphere (∼60–85 km). Since 2002, the radar was operated for a certain number of days ...
