摘要：

In a number of recent papers [J. Schmiegel, Ph.D. Thesis, TU Dresden, 2002], [http://www.maphysto.dk], [Usp. Mat. Nauk 159 (2004) 63], [Phys. Lett. A 320 (2004) 247], a continuous spatio-temporal process based on the integration of Levy bases was proposed to describe the statistics of the turbulent energy dissipation. An immediate consequence of this model is self-scaling of dissipation correlators, similar to the concept of extended self similarity (ESS) for velocity increments. We report empirical findings about self-scaling of dissipation correlators that support the Levy based dynamical modeling of the energy dissipation. (c) 2005 Elsevier B.V. All rights reserved.
