Abstract

This paper presents a new combined laser Doppler velocimetry-laser Raman scattering (LDV-Raman) apparatus which simultaneously measures velocity and scalars. Measurements in a ducted nonpremixed turbulent flame using this apparatus are presented and compared with previous LDV-Mie and LDV-Rayleigh measurements. A partial equilibrium numerical model of the hydrogen flame herein investigated predicts the major species to be at their equilibrium concentration while radical species, such as hydroxyl, can have mean concentrations that are three times greater than their equilibrium concentrations.
