Gardon型热流传感器隔热技术的优化

Improvement of Adiabatic Technique of Gardon Heat Flux Sensor

在无法向外散热的情况下,采用Gardon型热流传感器测量火焰强度的热流密度时,传感器对于热量的处理只能选择用储热体来吸收,故该类型的传感器有了工作时间的限制。为增加Gardon型热流传感器的工作时间,对其隔热技术加以改进,效果较为明显。

The Gardon heat flux sensor uses heat reservoir storing heat while measuring the flame＇s heat flux without heat dissipation. This is the reason why the working time of the sensor is restricted. By improving the sensor＇s adiabatic technique, the working time of the sensor can be prolonged. This paper describes the improvement of Gardon heat flux sensor＇s adiabatic performance, and carries out relative simulation and experiment. At last, the purpose of increasing the working time of the sensor is arrived.
