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 ...
Características da esteira turbulenta do modelo de um aerogerador
(Universidad Federal de Santa María, 2015)
O estudo experimental das características da esteira turbulenta a sotavento do rotor de uma
turbina eólica é realizado no túnel de vento “Joaquim Blessmann” da UFRGS. A complexidade do
escoamento turbulento é avaliada a ...
Wind tunnel experiments with neutral and convective boundary layer stabilities
(Scientific & Academic Publishing, 2018)
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. ...
Escoamento na esteira de turbinas eólicas : análise espectral da turbulência mediante testes em túnel de vento
(Universidade Federal de Santa Maria, 2016)
A interação entre o vento incidente e os aerogeradores em um parque eólico provoca déficit de velocidade, no caso de geradores sucessivos, e aumento nos níveis de turbulência na esteira das turbinas eólicas. O escoamento ...
Turbulence spectral characteristics of surface boundary layer
(Universidade Federal de Rio Grande do Sul, 2015-06-21)
A spectral analysis from wind tunnel and near-neutral atmosphere data was realized. The measurement spectra are compared with von Kármán and Kaimal expressions and a complementary evaluation based on the previous work of ...
