Abstract

This paper illustrates the use of air-coupled ultrasonic tomography for the measurement of a high-temperature flame from a natural gas burner, using capacitive ultrasonic transducers in through transmission. This uses a transducer pair, which is scanned in two-dimensional sections at several angles to the jet axis. Travel-time data then is recorded along various paths in counter-propagating directions. By processing the data obtained from propagation times, images have been formed of variations in temperature within the flame, using the tomographic reconstruction approach.
