Temperature, Concentration and Velocity Measurements in a Jet and Flame.

Abstract

The applicability of laser diagnostic techniques to flow field measurements is explored. Data obtained on a turbulent jet are compared with more conventional measurements. Specie concentration and temperature measurements were obtained from the ratio of vibrational Stokes to Anti-Stokes intensities using the single pulse Raman scattering technique, and velocity measurements were obtained using a laser Doppler velocitymeter. A preliminary attempt at applying the Raman scattering diagnostic technique to the concentration and temperature measurements in a simulated limited accessibility internal combustion chamber is very promising. Finally, the problem of data acquisition and reduction, and some remarks on the accuracy and precision are given.
