WebJul 1, 1993 · Abstract. We report on the existence of a hitherto undetected form of self-similarity, which we call extended self-similarity (ESS). ESS holds at high as well as at low Reynolds number, and it is characterized by the same scaling exponents of the velocity differences of fully developed turbulence. Received 9 November 1992. WebFractals: A fractal is a never-ending pattern. Fractals are infinitely complex patterns that are self-similar across different scales. They are created by repeating a simple process over and over in an ongoing feedback loop. … top rated coffee makers 2017

On Self-Similar Decay of a Plane Momentumless Turbulent Wake

WebOct 28, 2013 · Hence the self-similarity assumed in K41 may actually be broken. Presently the scaling exponents \(\zeta_p\) are known with an accuracy of a few percent and could well be universal, that is independent of the mechanism by which the turbulence is driven. Obtaining better evidence for or against universality is important. WebIntermittent turbulence in self-similar cascades: divergence of high moments and dimension of the carrier Abstract. Kolmogorov's “third hypothesis” asserts that in … WebMay 16, 2001 · The self-similarity further suggests that the vertical spectrum of horizontal kinetic energy of pancake turbulence should be of the form E (k z )∝N 2 k z −3, giving an alternative explanation for the observed vertical spectra in the atmosphere and oceans.
