AVAILABILITY AND PROBLEMS OF SIMULATED THERMAL IMAGE USING SMOOTHING TECHNIQUE : Fundamental study on thermographic survey by simulated thermal image using smoothing technique (Part 1)

Abstract

The thermographic survey using thermal imager is considered to be a method detecting the surface temperature differences between the delaminated area and the sound area of finishing materials on building walls. So, there exist some analytical studies using heat balance simulation on this method. However the numerical results obtained by a heat balance simulation can not always represent the easiness of judgement. In this study, the availability and problems of the simulated thermal images using finite element method with smoothing technique are discussed by comparing with the thermal images of test specimens.
