説明
<p>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 measurement technique with high sensitivity and high response, laser diagnostics 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 noncontact and fast response 2D temperature and concentration distribution measurement method. The method is based on a computed tomography(CT) technique using absorption spectra of water vapor at 1388nm. The CT tunable diode laser absorption spectroscopy method was applied to a burner and engine exhausts to measure 2D temperature distributions using 8-path, 12-path, and 16-path CT cells and the accuracy and the special resolution of this method was discussed compared with the measurement results of a thermocouple. Since CT tunable diode laser absorption spectroscopy has a potential of the kHz response time, this method enables the real-time 2D temperature measurements to be applicable in various industrial processes including engine applications.</p>
