ONE EXACTLY SOLUBLE MODEL IN ISOTROPIC TURBULENCE
Z. Ran (P. R. China)
Abstract:
The starting point for this paper lies in the results obtained by Sedov [25] for isotropic turbulence with the self-preserving hypothesis. A careful consideration of the mathematical structure of the Karman-Howarth equation leads to an exact analysis of all possible cases and to all admissible solutions of the problem. This paper revisits this interesting problem from a new point of view. Firstly, new solutions are obtained. Based on these exact solutions, some physically significant consequences of recent advances in the theory of self-preserved homogenous statistical solution of the Navier-Stokes equations are presented. New results could be obtained for the analysis on turbulence features, such as the scaling behavior, the spectrum, and also the large scale, as well as the small scale dynamics. The general energy spectra and their behavior in different wave number range are investigated. Extensive comparisons are made between these solutions and previous work.
Keywords and phrases:
isotropic turbulence, Karman-Howarth equation, exact solution.
