Fundamentals of the Temperature Measurement Method of Flames

Abstract

Temperature is one of the most important information for flame researchers among many characteristics of the flame so that many methods to measure it have been studied and developed. Originally, those were static and point measurement but nowadays, they are time-dependent and three dimensional. Even the methods have been drastically developed, the accuracy of the obtained temperature should be ascertained. This report will look back on the most reliable calibration method, though it is very old and looks unrefined.
