Two-color thermally sensitive phosphor coatings for temperature measurement

  • 摘要: 空气动力表面温度和压力分布的精确测量对理解复杂流场内部机制和流体力学仿真模型的验证具有重要意义。热敏磷光表面测温技术作为一种面测量技术,具有非接触测量、可对试件全尺度测量、空间分辨率高等优点。开发了一种室温到800 K 温度范围内的双色热敏磷光涂层材料。该发光材料受激辐射的发光光谱的两个发射峰光强在不同温度下呈现不同的衰减趋势,根据这种规律发展了双色测温技术。建立了热敏涂料温度标定系统,获得了双峰光强比与温度的变化曲线。采用双色法测温技术测量了旋转曲面物体表面的温度分布。结果表明,双色热敏磷光涂层测温技术能够实现物体表面温度的定量测量,对于测试技术的发展具有重要推动作用。

     

    Abstract: The accurate determination of spatially continuous temperature and pressure distribution on aerodynamic surfaces is critical for the understanding of complex flow mechanisms and for comparison with computational fluid dynamics predictions. Thermally sensitive phosphor coatings provide a way to obtain simple, inexpensive, full-field measurements of temperature with much higher spatial resolution. A new sort of two-color thermally sensitive phosphor coating was developed, which could be used to measure surface temperature between room temperature and 800 K. The various spectral regions in emission differ with temperature, which could be used to support the two-color temperature measurement method. The temperature calibration system was set up, and the intensity-ratio change curve as a function of temperature was obtained. The temperature distribution of curved surface was measured by two-color temperature measurement method. The results show that the two-color temperature measurement method has the ability of surface field temperature quantitative measurement.
