二色法を用いた高温ガス流れの温度速度同時計測

抄録

An aim of this study is to combine a two color phosphor thermometry with the Particle Image Velocimetry (PIV) for a measurement of gaseous flow at high temperature. A temperature distribution of heated wall was preliminarily measured using the developed two color technique, which estimated temperature from a ratio of luminescent intensities in different ranges of wavelength, 500 ~ 600 nm and 400 ~ 480 nm. Differences from measured temperatures by thermocouples were 7.8 ± 0.8 °C in maximum. A velocity distribution of an impinging jet was also preliminarily measured by the PIV with phosphor particles.
