Résumé / Abstract

A new method for the determination of thermocouple time constants is described, which reproduces the large temperature differences between the thermocouple junction and ambient fluid that occur in pressured turbulent flame applications. Time constants measured while the thermocouple is both heating and cooling, as well as the dependency of the time constant on velocity and temperature, are reported. Velocities are varied from 0.6 to 5.5 ms-1, and junction temperatures range from TOOK to 1500K while heating and from 400K to 1100K while cooling. Temperature differences between the thermocouple junction and ambient fluid up to 800K are achieved. Radiation losses from the junction are accounted for
