Description
Turbulence is ubiquitous in science, technology and daily life and yet,
despite years of research, our understanding of its nature is still far
from complete.
The talk presents a review of studies of the fundamental nature of
turbulence, in the light of high resolution direct numerical simulations of
turbulence. An emphasis is placed upon the examination of the idea of
celebrated Kolmogorov's theory on the existence of the universality in the
statistics at small scales in fully developed turbulence. A discussion is
also given on an application of the idea of linear response theory
developed in the statistical mechanics for non-equilibrium systems.
