"WebThese observations suggest that the Kolmogorov theory of homogeneous turbulence equilibrium cascade and of the resulting scale-by-scale energy must be a special case of a more general turbulence theory. To break beyond the Kolmogorov theory in a substantial way we need to break beyond its most constraining premises: equilibrium and homogeneity. " - The theory of homogeneous turbulence知乎
