Abstract

This work presents an experimental validation of an analytical model of heat conduction in spherical samples using infrared thermography. The theoretical model is a two dimensional analytical solution of the heat equation considering a radiant heating source. This model describes the physical behavior of the heat conduction in two dimensional solid objects considering spherical geometries. The model dependent on the radius and angle values and this is fit with the measured data using a thermal camera. A synthetic image obtained using this model is compared with the values obtained from a camera, for spherical geometry presenting good agreement
