Rapid tuning cw laser technique for measurements of gas velocity, temperature, pressure, density, and mass flux using NO.

Abstract

An intracavity-doubled rapid-tuning cw ring dye laser was used to acquire fully resolved absorption profiles of NO line pairs in the A ? X band at 225 nm at a rate of 4 kHz. These profiles were utilized for simultaneous measurements of flow parameters in the high speed 1-D flows generated in a shock tube. Velocity was determined from the Doppler shift… (More)
