Occurrence of turbulence in fluid dynamics from the equations of motion?
This argument must break down for those special cases where the usual turbulence doesn't occur, like 2D fluids. … But several people noted the enstrophy cascade would wreck the traditional ideas for why turbulence occurs
Generic nonlinear systems
The generic PDEs all have a turbulence, when they have a dissipation …

Have we figured out how to analyze turbulent fluids?
This is a much more difficult, and much more important problem, because it is the problem of turbulence. … It is the most significant advance in turbulence theory since K41. …

The equipartition theorem in momentum space
Nevertheless, this point of view is a useful first approximation to the turbulence problem. … The inability of fields to get to thermal equilibrium famously led to quantum mechanics, but it is also an important insight for the problem of classical turbulence. …
