Analysis of thermal and roughness effects on the turbulent characteristics of experimentally simulated boundary layers in a wind tunnel
(2022) [Journal article]The aim of this paper is to analyse the thermal effects in a wind tunnel experiment to simulate the planetary boundary layer (PBL). Experiments were performed in the wind tunnel of the Laboratory of Constructions Aerodynamics ... -

Employing wind tunnel data to evaluate a turbulent spectral model
(2016) [Journal article]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 the ... -

Flow in the wake of wind turbines : turbulance spectral analysis by wind tunnel test
(2016) [Journal article]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 ... -
Fluctuating velocity measurements in the turbulent wake of a wind turbine model
(2018) [Journal article]An experimental study of the turbulent wake of a wind turbine model was realized at the “Joaquim Blessmann” wind tunnel of the UFRGS. The turbine model was developed at the Universidade de Caxias do Sul and it represents ... -
Influência da turbulência atmosférica na esteira aerodinâmica de turbinas eólicas : estudo experimental em túnel de vento
(2017) [Dissertation]Aerogeradores, ou turbinas eólicas, são máquinas instaladas em grandes parques eólicos que convertem a energia cinética do vento em energia elétrica. A definição da separação e da interação entre máquinas é um fator ... -
Simulação do vento atmosférico e dos processos de dispersão de poluentes em túnel de vento
(2006) [Thesis]O estudo experimental dos processos de dispersão atmosférica de poluentes permite a análise de problemas específicos e a avaliação dos modelos teórico-numéricos. Os custos da experimentação de campo conduzem à realização ... -
Study of gas turbulent dispersion process in the Alcântara Launch Center
(2018) [Journal article]The Alcântara Launch Center (ALC) is the Brazilian gate to the space located at the north coast of Maranhão State, close to the Equator. Topographical local characteristics modify the parameters of incident atmospheric ... -
Wind tunnel experiments with neutral and convective boundary layer stabilities
(2018) [Journal article]The present contribution reports on the status of the STROMA experiment. As a novelty a new experimental setup in a wind tunnel allows to simulate different stability regimes with vertical heat flux in either direction. ...
