Fluctuating velocity measurements in the turbulent wake of a wind turbine model
(Scientific & Academic Publishing, 2018)
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 ...
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 ...
The Lévy fractional Brownian motion family as a new paradigm in the modeling of turbulent wave-front phase
(Society of Photo-Optical Instrumentation Engineers, 2007-09-25)
In Perez et al. [J. Opt. Soc. Am. A 21 (10), 2004] we have given a general formalism to model the turbulent wave-front phase by using fractional Brownian motion processes. Moreover, it extends classical results to non- ...

CPM model applied to turbulent event detections
(Journal of Scientific and Engineering Research, 2019-05)
The present work shows the application of a change-point model (CPM), based on the Cramer von Mises test for turbulent structures detection in airflow. Specifically, it models the occurrence of vortices in the wake of an ...
Multifractality and the effect of turbulence on the chaotic dynamics of a He-Ne laser
(Spie, 2013-09)
We propose the use of multifractal detrended fluctuation analysis (MF-DFA) to measure the influence of atmospheric turbulence on the chaotic dynamics of a HeNe laser. Fit ranges for MF-DFA are obtained with goodness of ...
