Abstract(s)
Esta dissertação tem como objectivo contribuir para o desenvolvimento de um túnel
de vento subsónico para o ensaio de coroas de pás de turbomáquinas, a funcionar no
Laboratório de Mecânica dos Fluidos e Turbomáquinas da Universidade da Beira Interior
(http://fluidslab.ubi.pt). O trabalho começa com uma revisão bibliográfica sobre os túneis de
vento existentes na Europa, nos Estados Unidos e também em Portugal. No âmbito do
presente estudo foram projectados e construídos os elementos essenciais de um túnel para
ensaiar turbinas axiais, que constam da secção de admissão, secção de ensaio, sistema de
propulsão e difusor. A análise do escoamento do fluido de trabalho através do túnel foi
realizada com o auxílio de uma ferramenta CFD comercial, o Fluent™ 6.3. As simulações
efectuadas permitiram conduzir o dimensionamento da morfologia do túnel de acordo com
critérios padrão existentes. São apresentadas algumas das ideias desenvolvidas, com base nas
isolinhas cinemáticas e dinâmicas do escoamento. Para o projecto dos elementos foi utilizado
um software 3D CAD/CAE, o Solidworks® 2008. A construção dos elementos foi realizada pela
empresa Marsilinox, situada em Vale de Cambra. A dissertação inclui a memória descritiva de
todas as peças e dos processos de fabricação. O trabalho encerra com a discussão dos
resultados e das principais conclusões, a par de uma síntese do trabalho a realizar no futuro.
The present study is a contribution to the development of a subsonic wind tunnel for testing turbomachinery blade rows. The wind tunnel is to be installed at the Laboratory of Fluid Mechanics and Turbomachinery of Universidade da Beira Interior (http://fluidslab.ubi.pt). The work starts with a bibliographical search about the wind tunnels in Europe, USA and also in Portugal. Within the framework of the study the essential elements of the wind tunnel have been designed and manufactured, namely the inlet section, the test section, the propulsion set and the exhaust diffuser. The analysis of the working fluid flow has been done with the help of a commercial CFD software: the Fluent™ 6.3. The simulations enabled to find the morphology of the tunnel accordingly to standard criteria. Some of the ideas herein presented were obtained through the visualization of the kinematic and dynamic isolines of the flow field. To design all the different components of the machine a 3D CAD/CAE software Solidworks® 2008 has been utilized. The wind tunnel elements have been manufactured by Marsilinox, in Vale de Cambra. The present dissertation includes a descriptive of all the components and the manufacturing process. The work ends with a thorough discussion of the results and the conclusions, in parallel with work to be pursued in the future.
