Caracterização de velocidades médias e padrões de turbulência do escoamento em escadas para peixes por bacias sucessivas com orifícios de fundo
(2012) [Artigo de periódico]A construção de barramentos ao longo dos rios causa muitas alterações no meio envolvido. Entre estes impactos, tem-se a formação de uma barreira que impede o deslocamento dos peixes interferindo principalmente na reprodução ... -
Estudo experimental das características do escoamento em escadas para peixes do tipo ranhura vertical : turbulência do escoamento
(2011) [Artigo de periódico]A construção de barramentos ao longo dos rios causa muitas alterações no meio envolvido. Entre estes impactos, tem-se a formação de uma barreira que impede o deslocamento do habitat aquático, interferindo, principalmente, ... -
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 ... -
Large eddy simulation of three-dimensional turbulent flows by the finite element method
(2006) [Artigo de periódico]The main objectives of this work are the formulation, implementation and applications of a numerical algorithm to simulate turbulent, incompressible, isothermal flows. The transient three-dimensional flow is analyzed using ... -
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 ... -
Numeric and experimental analysis of the turbulent flow through a channel with baffle plates
(2004) [Artigo de periódico]The present work presents the numeric and experimental analysis of the turbulent flow of air inside a channel of rectangular section, containing two rectangular baffle plates. This is an important problem in the scope of ... -
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 ...
