Determinação de áreas de vulnerabilidade à erosão hídrica com base na equação universal de perda de solo (USLE)
(Universidade Federal de Minas GeraisUFMG, 2015-08-14)
This research presents the application of Equation Universal of Soil Loss (USLE) in the determination of areas vulnerable to erosion area at upstream of PCH Salto do Paraopeba. The main factors of the physical and man-made ...
Análise computacional via CFD de uma turbina hidrocinética em condutos abertos
(Universidade Federal de Minas GeraisUFMG, 2019-02-15)
This work deals with the development of a computational procedure, based on a CFD commercial package, to analyze the behavior and the performance of hydrokinetic turbines. A preliminary performance analysis of three NACA ...
Estudo da velocidade de queda e do início do movimento das partículas de borracha e areia
(Universidade Federal de Minas GeraisUFMG, 2017-07-06)
The proper design of a dam depends on a set of studies and strategic decision-making, both strongly impacted by local constraints. Due to the fact that this type of enterprise usually consist in a large facility, several ...
Desenvolvimento de metodologia para determinação dimensional deuma bomba centrífuga utilizando velocidade específica (ns)
(Universidade Federal de Minas GeraisUFMG, 2017-02-20)
With an increased demand for sustainable energy, the use of centrifugal pumps to meet the countrys water supply needs - by pumping facilities, the industry in general and agribusinesses - has been widely applied towards ...
A influência da infestação pelo mexilhão dourado em condutos forçados das centrais geradoras hidrelétricas no Brasil: uma análise das perdas e do transiente hidráulico
(Universidade Federal de Minas GeraisUFMG, 2016-12-20)
The golden mussel is a bivalve freshwater mollusc that causes several environmental and economic problems wherever it is found. In Brazil, the first detection of this mollusc took place in the late 1990s. Among all the ...
Investigação experimental do comportamento de fraturas em tubos de PVC submetidos à variações de pressão
(Universidade Federal de Minas GeraisUFMG, 2015-08-18)
Water losses are known problems in the sanitation sector. However, the identification and correction of physical losses is not trivial task, especially where there is no effective management of mesh pipelines and pressures ...
Uso da água de chuva para repor perdas por evaporação em processos de laminação a quente de aço
(Universidade Federal de Minas GeraisUFMG, 2017-02-13)
Awareness about the importance of the rational use of water resources and concern about water pollution in the world is increasingly needed. The reduction of operating costs has been a competitive differential between the ...

(Universidade Federal de Minas GeraisUFMG, 2013-07-08)
This paper presents a study of the interference of temporal factors on the results of the testing of swimming performance of fish. For this study we developed a varying time increments used for testing of swimming performance. ...
Reconstituição da calha natural do reservatório da PCH Salto do Paraopeba
(Universidade Federal de Minas GeraisUFMG, 2014-08-08)
The Salto do Paraopeba power plant reservoir is silted since the early 2000s, being the focus of this study to determine its primitive geometry. It is noteworthy, however, that there is no data from the original bathymetry ...
Determinação das regiões de passagem de peixes em um modelo físico de MTP tipo ranhura vertical
(Universidade Federal de Minas GeraisUFMG, 2018-06-29)
The reservoirs are part of the landscape in most of the basins of Brazil. In many cases, dams can be an ecological barrier that cannot be overcome by some species of fish, especially those that need the freedom of upward ...
