Static and stagnation temperature measurements are performed by CARS and by an intrusive probe in a Mach 2 cylindrical jet of hydrogen, injected into a Mach 2 coflow of air. The single-shot CARS static temperature measurements are based on nitrogen. A stagnation temperature probe has been developed and tested. This method consists in identifying the transient regime of a thermocouple probe with a numerical prediction modeling the high speed effects on the probe recovery factor. The paper presents and discusses the comparison between the temperature measurements performed by the intrusive probe and the CARS non-intrusive techniques (1) at the inlet of the combustion chamber, (2) in the ignition zone of the hydrogen jet; (3) in the burnt gases.
