| 摘 要： | 针对高超声速风洞试验中对高频热流脉动的测试需求，研制了一种基于横向热电效应的原子层热电堆（Atomic Layer Thermopile，ALTP）热流传感器。利用弧光灯热流传感器标定系统对其进行静态标定，获得ALTP热流传感器的灵敏度系数约为8.24 μV/（kW·m-2），优于国外同尺寸敏感元件的ALTP热流传感器6.90 μV/（kW·m-2）的灵敏度系数；利用激波风洞试验，并通过与薄膜热电阻热流传感器对比，初步获得ALTP热流传感器的响应时间上限，响应时间小于0.20 μs。

| Abstract: | The transverse Seebeck effect is used to develop the ALTP heat-flux sensor for the high-frequency-pulse heat flux density measurement in hypervelocity wind tunnel tests. The self-innovated ALTP heat-flux sensor is statically calibrated with the xeon short arc lamp calibration system. And the sensitive coefficient is about 8.24 μV/(kW·m-2), which is larger than the sensitive coefficient 6.90 μV/(kW·m-2) of the ALTP heat-flux sensor developed abroad. Then an experiment was conducted in a shock wind tunnel to get the sensor's response time in comparison with thin-film-resistance heat-flux sensors, and the response time of the ALTP heat-flux sensor is less than 0.20 μs. |
