Title: Experimental heat transfer studies with infrared camera
Authors: Jimenez Sanchez, Carlos
Abstract: The master thesis described on this report consists on two experimental heat transfer studies using infrared thermography technology. The first part, the temperature evolution of two cooled surfaces is studied. Representing the thermal effect suffered by the pistons during the process of injection in diesel engines. The results are compared with CFD simulations and with thermocouple measuremnts that were done previously. This study is useful to understand better the reasons why pistons are damage and to constrast the different methods. In the second part, the convection heat transfer coefficient inside a linear cascade is studied. This coefficient is measured on a instrumented end-wall, showing the thermal behavior between the vanes and wall interaction. Measuring convection heat transfer coefficient on the endwalls can provide a better understanding of the heat transfer mechanisms in OGVs section. This enables the posibility of optimizing the coolant needed in this section and the material taht can be used for manufacturing OGVs, i.e; composite material are lighter than metal but they have lower melting temperature. Moreover, as in the other experiment the data can be compared with other methods and contrasted with CFD simulations. Furthermore, another goal of the experiment is to validate this methodology and technique to get this data.
