Title: Experimental Heat Transfer Study in Intermediate Turbine Duct
Authors: Perez, Borja M. Rojo
Abstract: This master thesis report presents an experimental study of the heat transfer in an agressive intermediate turbine duct (ITD). The aim of this study is the visualization of a surface temperature distribution and convection heat transfer coefficient with a very high resolution and precision of vane which is located inside the ITD in order to understand the heat transfer mechanism in the intermediate duct. The intermediate turbine ducts are used in modern jet engines to guide the flow from the high-pressure turbine (HPT) to the low-pressure turbine (LPT). This experiment was done in a state-of-art aggressive intermediate turbine duct in a large-scale low-speed turbine facility. The purpose of this design is to have a realistic inlet conditions and a Reynolds number. The measurements were performed by using the Infrared Thermography. In order to use this method, an infrared imaging camera is necessary and vane has to be specially prepared and instrumented. The results of this experiment will be used for CFD validation and these results will help to understand the heat transfer mechanisms inside the ITD. First of all, I would like to express my gratitude to my supervisor Martin Johansson. His patience from the beginning when I did not know hardly anything about laboratory equipment and his support during all the time that I spent doing my paper were of invaluable help.
