Application of photon correlation to turbulent fluid mechanics

The photon correlation technique is used in several turbulent fluid investigations, whose various results highlight the significant advantages and disadvantages of the photon-resolved processor. Although lack of control over the particle size distribution of light scatters, and the lengthy experimental time required for a photon-resolved autocorrelation curve, are noted as disadvantages, credible mean velocity measurements can be made in flow configurations which would be inaccessible using the counter and/or tracker techniques.
