Abstract

Illuminant is a porous media consisting of powder materials. The flame of illuminant seems continuous, but in fact the flame is made up of a substantial number of burning particles, and the burning particles determine the temperature distribution of the flame. In this paper, the distribution of the burning particles was first studied using a high speed camera. Then a model of the temperature field of illuminant flame was established based on the equation of heat conduction and the distribution function of the burning particles. The temperature field of the illuminant flame was predicted by the model and the highest temperature was measured using Fourier transform infrared spectrometer. The model was validated by the experimental results using an infrared thermometer. The results indicate that a good match has been achieved between the experimental data and the model predicted flame temperature field of the illuminant based on the distribution of burning particles.
