Abstract

Two dimensional (2D) temperature and concentration distribution plays an important role for the combustion structure and the combustor efficiency in engines, burners, gas turbines and so on. In high temperature and pressure fields such as engines, the non-contact 2D temperature distribution cannot be attained by thermocouples, which are intrinsically a point measurement method. In this study, the experimental research has been conducted in order to develop the non-contact and fast response 2D temperature and concentration distribution measurement method in high pressure and high temperature fields using CT-tunable diode laser absorption spectroscopy (TDLAS).
