National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Universal Law for Tails of Density PDF's in Multi-Dimensional Burgers Turbulence.

DE2001763998

Publication Date	2000
Personal Author	Bec, J.; Frisch, U.
Page Count	7
Abstract	Extending work of E, Khanin, Mazel and Sinai (1) on the one-dimensional Burgers equation, we show that density pdfs have universal power-law tails with exponent -7/2. This behavior stems from singularities, other than shocks, whose nature is quite different in one and several dimensions. We briefly discuss the possibility of detecting singularities of Navier Stokes turbulence using pdf tails.
Keywords	Turbulence Burgers vector Probabilistic estimation Many-dimensional calculations Navier-Stokes equations
