Study on Dynamical Properties of Intermittent Phenomena in Turbulent Boundary Layer
Abstract
Following the idea proposed previously that describes the phenomena observed in the outer region of the turbulent boundary layer in terms of a onedimensional map generating the intermittent chaos, we attempt to analyze the problem with the use of statistical mechanical methodology applied frequently to dynamical systems. From the binary sequences constructed by processing measured data of instantaneous streamwise velocities, we obtain the singularity spectrum or the fluctuation of the dynamical scaling indices. In particular, the Kolmogorov entropy is given quantitatively as a function of the distance from the wall. The difference from random motions is emphasized.
