Abstract
Optical measurement techniques are more and more widely used to investigate the mixing processes in small and medium scale mixers. Most of these techniques (including LIF based techniques) suffer from principle problems when investigating and quantifying reacting processes. Within this work a Raman scattering test-bench has been set-up to investigate dynamic processes in more than one dimension. While the Raman scattering approach allows investigating concentrations of several components simultaneously in reacting and non-reacting fluids with high accuracy, it is normally restricted to one-dimensional measurements, which is not sufficient for characterization of mixing processes. So the technique was improved to a pseudo two-dimensional multipoint technique. This article deals in detail with the advantages, disadvantages and limitations of different approaches. Furthermore the technical details of the developed Raman scattering set-up are described.
