Research Abstract

The universality in the statistics of turbulent flows at high Reynolds number as well as the idea of the universality were examined on the basis of the analysis of the numerical data by large-scale direct numerical simulation. Particular attention was paid to (A) the universality inherent in the turbulence dynamics and (B) the universality of wall bounded turbulence. Study was also made on the method of coherent vortex simulation, which is based on the extraction of coherent vortices by the use of wavelet analysis and is expected to be useful for reducing the degrees of freedom to be treated in turbulence modeling.
