Abstract

A novel technique for making temperature measurements in combusting flows is described. This technique, thin-filament pyrometry, is based on the graybody emission of a small ceramic filament (15 μm), which is introduced into the flow field under study. The technique is applicable over the temperature range 1000–2600 K. The temporal response of the filament is a function of the velocity, constituents, and temperature of the flow field but under ambient conditions is ~750 Hz (1/e). The emission from the filament can be recorded over the entire length of the filament, allowing the complete spatial temperature distribution to be recorded.
