High temperature field application of two dimensional temperature measurement technology using CT tunable diode laser absorption spectroscopy
چکیده انگلیسی

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. Recently, as a multi-species measurement technique with high sensitivity and high response, tunable diode laser absorption spectroscopy (TDLAS) has been developed and applied to the actual engine combustions. With these engineering developments, transient phenomena such as start-ups and load changes in engines have been gradually elucidated in various conditions. In this study, the theoretical and experimental research has been conducted in order to develop the non-contact and fast response 2D temperature and concentration distribution measurement method. The method is based on a computed tomography (CT) using absorption spectra of water vapor at 1343 nm and 1388 nm. High temperature field application of two dimensional temperature measurement technology using CT-TDLAS has also been discussed to demonstrate its applicability for various types of combustor.
