In this report the viewer will find, firstly, an introduction to the theoretical basis of liquid crystal thermography as well as an explanation of the calibration process carried out in the laboratory. Secondly, a statement about the experiment developed to measure heat transfer coefficients and Nusselt numbers of a specific surface will be made. In this phase an overall description of the infrared thermography (IRT) will also be shown. In addition all the Matlab scripts used to process the data gathered can be found in the back up documents of this report. Finally the report includes a detailed analysis of the results obtained in both calibration and experimental work processes. Within this section the viewer will be able to find a discussion about main advantages and drawbacks of each technique (LCT and IRT) as well as explanations about error analyses among other issues. The main purpose of this project is to approach two different temperature measurement techniques that have been being applied in the recent years in many several fields of technology. Based on both the experimental and theoretical work done this project should allow us to get familiar with these techniques.
