Noise Thermometry Measurements in Combustion Processes.

Abstract

Experiments are described in which the temperature of combustion gases is measured by directly sensing the thermal noise emissions from the flowing gases. The temperatures measured by the noise thermometer are compared to reference thermocouple readings. Within the limitations of the reference thermocouple and the accuracy of the noise thermometer calibration standards, the temperature determined by direct noise thermometry appears to represent the true gas temperature and is uncomplicated by contaminating sources of electromagnetic noise.
