Abstract

Thermometry of hardware in high temperature combustion environments may be difficult and challenging to perform. Intrusive sensors, such as thermocouples, can significantly modify the local temperature field. Fatigue life of combustor components is a critical function of temperature. Methods based on the temperature-dependent emission properties of certain phosphors show promise in these situations. The temperature of an object, a variable area diffuser centerbody, immersed in an afterburner flame of a jet engine was measured. To our knowledge, this is the first report of a field application of the thermal phosphor technique in this type of environment. The testing, performed at Arnold Engineering Development Center, revealed that useful temperature measurements can be made. The objectives of this work were: (1) to provide a near-term solution to a thermal monitoring problem associated with jet engine testing, and (2) to investigate the phosphor technique for its potential in solving other envisioned thermal mapping problems in combustion and aerodynamic facilities.
