Abstract

By scattering light from a turbulent fluid seeded with small particles, one obtains information about turbulent velocity fluctuations over varying spatial scales, R. The measured intensity autocorrelation function,g(t), is related to the probability density P(V(R)) of finding velocity fluctuations of magnitude V(R) associated with eddies of size R. The measurements described here strongly suggest that the energy-containing eddies occupy a fractal region whose dimension (or spectrum of dimensions) increases with the Reynolds number Re when Re exceeds some threshold value.
