用二维(平面)激光诱导磷光法测定了加热的湍流空气射流的温度分布。射流被加热到特定的温度增量，范围从300-850K，并在每个温度下研究了几个雷诺数。光谱比技术分别与BAM和YAG：Dy热成像荧光粉结合使用。单次拍摄和时间平均的结果以湍流射流的二维叠加图像的形式呈现。对于单次激发测量，YY没有产生足够高的信号。结果表明，BAM更适合于较低的温度、快速和湍流区，而YAG：Dy更适合于较高温度、稳定流动的情况。
The temperature distributions of heated turbulent jets of air were determined using two dimensional (planar) laser induced phosphorescence. The jets were heated to specific temperature increments, ranging from 300 - 850 K and several Reynolds numbers were investigated at each temperature. The spectral ratio technique was used in conjunction with thermographic phosphors BAM and YAG:Dy, individually. Single shot and time averaged results are presented as two dimensional stacked images of turbulent jets. YAG:Dy did not produce a high enough signal for single shot measurements. The results allowed for a direct comparison between BAM and YAG:Dy, revealing that BAM is more suitable for relatively lower temperature, fast and turbulent regimes and that YAG:Dy is more suited to relatively higher temperature, steady flow situations.
