Abstract(s)
Os túneis de vento têm sido frequentemente utilizados para validar os resultados de modelos matemáticos aplicados aos estudos de coroas de pás de Turbomáquinas. Assim sendo, o presente trabalho tem como principal objectivo desenvolver um túnel de vento para ensaio de Turbomáquinas, a funcionar no laboratório de Mecânica dos Fluidos e Turbomáquinas da Universidade da Beira Interior. Numa primeira fase, foi necessário fazer uma revisão bibliográfica sobre os túneis de vento desenvolvidos para ensaio de Turbomáquinas a nível mundial. Durante a montagem do nosso túnel foram utilizados alguns elementos já projectados e construídos desde de 2011. Estes elementos foram ligados ao sistema de propulsão e são apoiados numa estrutura que foi por nós projectada no Solidworks® 2013 e construída nas oficinas gerais da UBI. O Túnel foi posteriormente ensaiado e os resultados obtidos foram comparados com as previsões do modelo computacional realizado com o Fluent® 2016. O trabalho desenvolvido culminou numa instalação funcional com grande potencial para o futuro desenvolvimento de turbinas a gás no Laboratório.
Wind tunnels have often been used to validate the results of mathematical models applied to Turbomachinery blade rows studies. Therefore, the main objective of this work is to develop a wind tunnel for Turbomachinery testing, to be used at the Laboratory of Fluid Mechanics and Turbomachinery of the Universidade da Beira Interior (UBI). In the first stage of this study it was necessary to carry out an extensive bibliographical review on the wind tunnels developed worldwide for Turbomachinery testing. During the assembly of our tunnel we used some elements that were already designed and built since 2011. These elements were connected to the propulsion system and are supported on a structure that was designed by us using Solidworks® 2013. This structure was built in the general workshops of UBI. The tunnel was then tested and the results were compared with the predictions of the computational model obtained using Fluent® 2016. The high point of this research was the development of a functional installation with great potential for the future of gas turbines in the Laboratory.
