Determination of regular structures in turbulent mixing processes by Raman scattering
Abstract
A Raman scattering technique is described which is capable of detecting and analyzing regular structures in the flow. The technique relies on the measurement of the time autocorrelation function of the Raman signal together with the measurement of the amplitude distribution. It is shown that the spatial and temporal distribution of a single gas component in the flow field can be determined with a time resolution of 150 microsec using the new technique.
