Abstract
The present work presents a critical review of the literature concerning Infrared Thermography applied to the investigation of the boiling phenomena. The infrared thermography presents the following advantages over the traditional methods of temperature measurement: (i) fast time response; (ii) high accuracy; (iii) does not affect the temperature field (non-intrusive) under analyses, (iv) provides local and superficial temperature distribution. However, to achieve reliable data measurements using this technique several aspects concerning the test section design should be carefully evaluated. Several sources of measurement errors, especially regarding optical issues of the composing materials must be correctly addressed. Therefore, different approaches were adopted in literature to the test section design, calibration of the IR camera and data regression procedure. These different approaches are analyzed and their advantages and restrictions are discussed.
