Turbulence is best described as what it’s not: Laminar flow. Turbulence contains high vorticity.
But turbulence is not vorticity. It is:
- chaotic (small changes to initial conditions result in large changes to resulting patterns)
- diffusive (diffusing energy & momentum from isolated parts of fluid to the rest)
There is not a single, agreed upon criterion for turbulence. Richard Feynman described it as the most important unsolved problem in classical physics.
Turbulence can be analyzed using, traditionally, the Navier-Stokes Equation Escrichs2022
- In neuroscience, the Kuramoto order parameter is often used, based on Deco2020.
