概要

• To understand how entropy (T^2/2) is cascaded to smaller scales and kinetic energy is transferred to larger scales, temporal evolutions of the entropies and the energies distributed into several scales by 2D wavelet are examined numerically. The correlation coefficient of entropy between adjacent scales has a sharp peak and the delay time giving this peak is scaled as k^<-2/5>. The direction of energy transfer is not fixed but reverses occasionally between normal and inverse.
