Análise de macroturbulência em estruturas de dissipação de energia por meio de estudo de variação de pressões e níveis
(2004) [Artigo de periódico]O conhecimento do processo de dissipação de energia em canal com emprego do ressalto hidráulico passa, obrigatoriamente, pela determinação das características da distribuição longitudinal de pressão junto ao fundo do ... -
Analysis of thermal and roughness effects on the turbulent characteristics of experimentally simulated boundary layers in a wind tunnel
(2022) [Artigo de periódico]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) [Artigo de periódico]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 ... -

Fluctuating velocity measurements in the turbulent wake of a wind turbine model
(2018) [Artigo de periódico]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 ... -
A genuine solution of the diffusion advection equation sesquilinear way to multi-source problem
(2016) [Artigo de periódico]The present work is a proposal for an alternative approach for pollution dispersion modelling, including some characteristics that may be associated to the phenomenon of turbulence. As a starting point we consider two ... -
A numerical study of the influence of radiation on turbulence in a 2D axisymmetric turbulent flame
(2015) [Artigo de periódico]This paper presents a study of the influence of thermal radiation on turbulence in the simulation of a turbulent, non-premixed methane- air flame. In such a problem, two aspects need to be considered for a precise evaluation ... -
The influence of stable stratification on the transition to turbulence in a temporal mixing layer
(2006) [Artigo de periódico]The transition to turbulence in a stably stratified flow is a problem of considerable interest in fluid dynamics with applications in both geophysical sciences and engineering. This transition is controlled by competition ... -
Three-dimensional numerical simulation of flow in vertical slot fishways : validation of the model and characterization of the flow
(2019) [Artigo de periódico]Vertical slot fishways allow energy dissipation as a function of the pool, longitudinal slope, baffle and vertical slot design. The mean and turbulent flow patterns in these structures must be compatible with the fish ...
