PIVとLIFを用いた円筒管内における振動流のエンタルピー流測定

抄録

The measurement of an acoustic field in a resonance tube is important for the development of the thermoacoustic engine. Measurement of a temperature field in the thermoacoustic engine has been using a thermocouple so far, but it is difficult to investigate thermoacoustic phenomena occurring in engine core in detail. In this study, in order to make clear temperature field in heat exchangers and regenerators, two color toluene Laser Induced Fluorescence (LIF) is employed. As the first approach for the measurement by toluene two color LIF, temperature field by simple heat conduction of air in the glass tube, where temperature gradient are given, is visualized.
