1. Study of the electricity consumption reduction of a compressed air system: the case of a steelmaking company
Abstract This work aims to reduce the energy consumption and thus increase the availability of blast furnace compressors of a steelmaking company, located in Alto Paraopeba region in Minas Gerais state, Brazil, through the elimination of waste points in the compressed air distribution. In order to develop this work, an ultrasound test in the compressed air l

2. Genetic algorithm for preliminary design optimisation of high-performance axial-flow compressors
This work presents an approach to optimise the preliminary design of high-performance axial-flow compressors. The preliminary design within the Gas Turbine Group at ITA, is carried on with an in-house computational program based upon the streamline curvature method, using correlations from the literature to assess the losses. The choice of many parameters of

3. Dimensionamento de uma rede de distribuição de água de resfriamento para um compressor de ar / Pipe sizing for a distribution of cooling water for an air compressor
No presente trabalho é realizado um estudo do sistema de resfriamento de um compressor de ar com a finalidade de reduzir o aquecimento excessivo da máquina. O sistema é resfriado à água que é bombeada das torres de resfriamento para o compressor. O ar comprimido gerado é utilizado para fabricação de garrafas PET de uma companhia de bebidas. A metodo

4. An analysis of the energy efficiency of piston compressors in compressed air systems / Análise da eficiência energética em compressores a pistão em sistemas de ar comprimido
Este estudo analisa a eficiência energética de compressores a pistão e seu consumo de energia elétrica utilizando motores-padrão e de alto rendimento acionados por partida direta e com softstarter. A influência de vazamentos sobre a eficiência energética foi também analisada, assim como os valores de corrente, potência, fator de potência e taxas d

5. Análise de eficiência energética em sistemas de ar comprimido
The compressed air systems represent plot expressive of energy consumption of an industrial plant. However, the lack of an appropriate project and a regular maintenance causes reduction in the overall performance featuring a constant source of waste. This fact guided the subject of this dissertation research, which is directed towards the development and app

6. Diagnosis of the use of electric energy of slaugterhouse chicken emphasing action of energy efficiency / Diagnostico do uso de energia de um frigorifico de frangos de corte enfatizando medidas de eficiencia energetica
In the slaughterhouses the operations that if unchain in the one before slaughter until the storage of the end item are intensely dependents of the electric energy and answer for the final product quality. This work had as objective to diagnosis, to analyze and to consider solutions that lead to the rational use of the electric energy without intervening or

7. Conservação de energia em edificios comerciais atraves da implementação de dispositivos de automação / Conservation of energy in commercial buildngs through the implementation of automation devices
This work comes to present a panorama of the electric system found usually in commercial constructions of great load, with about thirty years of operation, that operate in way a little efficient for the current parameters, mainly in her air conditioning system. In that construction (in study), her system of environmental conditioning represents an increment

8. Numerical simulation of axial flow compressors.
This work deals with the numerical simulation of axial flow compressors, from design to performance prediction. The stage performance prediction uses the meanline flow properties. Stage-stacking is used to analyse a multi-stage compressor. A computer program, written in FORTRAN, was developed and is able to design an axial flow compressor given air mass flow

9. Estudo de transferencia de oxigenio em reatores tipo air-lift utilizando venturi e peças cisalhantes
The application of air-lift reactors in wastewater treatment is very attractive, when compared to the conventional ones, as they show high air to water oxygen transfer rates from, with great possibility of treating wastewater with high pollutants concentration with moderate costs. The use of venturis and centrifugal pumps as means of promoting air-lift react
