Resumo
Os avanços tecnológicos e o crescimento da cadeia produtiva brasileira geram uma demanda cada vez maior de energia para suprir as necessidades dos processos industriais. Este crescimento torna necessário um maior investimento em pesquisas para a otimização de processos produtivos, tornando-os autossustentáveis, com baixo custo e gerando menor consumo de energia primária possível. É neste sentido que a cogeração e a exergia atuam de uma forma efetiva no desenvolvimento do presente estudo, que tem como principal objetivo a realização de um projeto, sua execução e análise de uma máquina de fluxo tangencial de fabricação simplificada. Para tanto, foram adotadas teorias de máquinas de fluxo e mecânica dos fluidos. Para o dimensionamento dos elementos construtivos da máquina de fluxo, foi aplicada a equação do balanço de exergia, da primeira lei da termodinâmica, do princípio da conservação de massa, da quantidade de movimento linear e angular. O presente estudo é de natureza aplicada, de abordagem quantitativa, com caráter exploratório e descritivo, no qual possuem procedimentos técnicos experimentais e de estudo de caso. Utilizando a metodologia desenvolvida, foi possível atingir em todos os testes realizados o objetivo principal deste trabalho, que foi a geração de potência mecânica no eixo de 1000 W. Realizaram-se três testes com três pressões diferentes, nos quais em todas as condições propostas atingiram o objetivo, ou seja, a potência mecânica no eixo da máquina de fluxo tangencial foi de no mínimo 1022 W. Desta forma realizou-se um comparativo com o dimensionamento realizado inicialmente, apresentando uma eficiência de 18,63%, o que para este caso foi considerado satisfatório.
Technological advances and the growth of Brazilian production chain generate an increasing demand of energy to meet the needs of industrial processes. This growth is necessary for greater investment in research for the optimization of production processes, making them self-sustaining, low cost and generating less possible primary energy consumption. It is in this sense that cogeneration and exergy act in an effective way in the development of this study, which aims to carry out a project, execution and analysis of a tangential flow machine simplified manufacturing. Therefore, theories were adopted from flow and fluid mechanics machines. For the design of the constructive elements of the flow machine, was applied to the equation of exergy balance, the first law of thermodynamics, the principle of mass conservation, the amount of angular and linear movement. This study is an applied nature, quantitative approach with exploratory and descriptive, which have experimental technical procedures and case study. Using this methodology, it was possible to achieve in all tests the main objective of this work, which was to generate mechanical shaft power 1000 W. There were three tests with three different pressures, in which in all proposed conditions reached the goal, that is, the mechanical power on the shaft of the tangential flow machine was at least 1022 W. Thus was carried out a comparison with the design carried out initially, with a 18.63% efficiency, which in this case it was considered satisfactory.
