Development of Measurement Technique for High Temperature Flame FieldYANG Chun-hu, WANG Hai-sheng Dept. of Mathematics and Physics, Shanghai University of Electric Power, Shanghai 200090, ChinaAbstract:Some commonly-used high temperature flame measurement techniques are introduced. Their theories, methods and characters are expounded and compared. The measurement method based on radioactive theory, is simple and mature, especially colorimetric temperature-measurement method which is widely used. Spectroscopy diagnosis technique is good at high resolutions in both time and space, With the development of laser and image device, CARS and LIF technique become the hot subject in investigation. The temperature measurement based on laser interferometry is nonintrusive. It can get the accurate high-temperature field quantitatively.[著者文摘]
