Multiphysics study of infrared thermography (IRT) applications

Abstract

Infrared thermography is the science of detecting infrared energy emitted from an object, converting it to apparent temperature, and producing images of that radiation, called thermograms. Infrared thermography means "beyond red temperature image". IR thermography being a remote non-contact/non-destructive means of testing is perfectly suitable for tests in extreme environments. Also, it is fast, reliable, and detailed. Due to the advantages offered by IR thermography, it is being employed in various industries. Infrared thermography (IRT) has a long history in industrial applications; however, its use is increasing exponentially in the research and development sectors. Academic and research institutions are finding IR thermography as one of the fundamental tools for teaching and research. This review paper discusses studies where IR thermography has been used effectively in research and development projects at the UiT The Arctic University of Norway. The applications discussed in this work are: · Thermal conductivity and heat transfer coefficient of freshwater and marine ice. · An industrial solution for detecting icing. · Determine relative required insulation (IREQ) of clothes. · Surface temperature of steel samples under tensile testing at room and cold temperatures.
