Abstract

CO2 and N2 jets issuing into air from small rectangular channels of 2x25 mm cross section were investigated. Concentration measurements were obtained by cw-laser Raman spectros-copy; gradients larger than lo vol. %/100 µm could easily be resolved; spatial resolution was better than lo -2 mm3 and the measured fluctuations of the Raman signals show satisfactory agreement with Poisson statistics. Axial and radial profiles are reported for single and multiple jets and comparison with theory is given, where possible.
