Abstract为了测量超燃冲压发动机燃烧室的热环境,从Gardon热流计原理出发,发展了一套水冷热流/壁温一体化测量技术。采用热阻分析方法,对传感器的热结构进行了分析与优化设计。测试了多种隔热与外壳材料对传感器响应特性的影响。通过辐射加热方式对传感器进行了标定,获得了热流/电压、壁温/热流的标定曲线。采用该传感器,在模拟马赫数6、总温1800K的来流条件下,对超声速燃烧室的热环境进行了初步测量,获得了与传热分析相一致的结果。
Other AbstractTo study the thermal environment of a scramjet combustor, a water-cooled heat flux/wall temperature measurement technique has been developed based on the principle of Gardon heat-flux sensor. Method of heat resistance analysis has been used to design the thermal structure of the sensor. Effects of materials and structure on the sensor's responses have been determined. Calibration processes using radiative heating sources were carried out and calibration curves of heat flux vs voltage and wall temperature vs heat flux were obtained. Preliminary measurements were carried out on a supersonic combustor at flow conditions of Mach 6 at total temperature 1800 K. The experimental results showed a good agreement with that of a heat transfer analysis.
