On Small-Scale Intermittency for General Turbulence

Abstract Deviating from homogeneous isotropic turbulence, we analyze a large amount of experimental data with respect to the dimensionless dissipation constant, the intermittency parameter, and the multiplicative noise in a corresponding stochastic process description of the cascade. We find that all three parameters are strongly related to each other. Although these parameters contain quite different information about turbulence, it is sufficient to know one to estimate all other parameters. This suggests that our results imply a new generalization.
