Specie concentration measurement in a free jet flow utilizing Raman scattering of a laser beam
Abstract
Nonintrusive flow field measurements have received great attention, where the presence of a physical probe would cause an unacceptable perturbation to the system under study. Molecular Raman scattering is well suited to obtain local measurements of individual gas densities and gas temperatures. In this paper we discuss briefly where vibrational Raman scattering is used to determine the actual number of molecules in a multicomponent gasmixture.
