Randomized trial validates a novel laser diagnostic for measuring temperature and pressure in high-speed flows, indicating its effectiveness.

Key Points

This research aims to develop and validate a laser diagnostic technique for temperature and pressure measurements in high-speed and high-temperature environments.
Developed a spectrally resolved laser-induced fluorescence diagnostic for nitric oxide in argon and nitrogen gases.
Conducted static cell and shock tube experiments for validation across a temperature range of 295–1350 K and pressures of 2.1–47.0 kPa.
Created a fluorescence model to simulate processes and assess the measurement rate.
Validation experiments showed a 3.0% average error in temperature readings within the validated range.
The diagnostic achieved a 5.5% average error in pressure measurement for collisional-to-Doppler width ratios greater than 0.30.
Experimental findings align closely with known values, confirming the diagnostic's reliability.
