Navier–Stokes turbulence shows sensitivity in statistics
What the study found The study reports that Navier–Stokes turbulence can show “ultra-chaos,” meaning that very small changes in starting conditions can lead to large differences not only in the flow path but also in flow symmetry and statistical behavior. The authors present this using two-dimensional turbulent Kolmogorov flow as an example. Why the authors…
Structure-preserving simulations show differing turbulence behavior
Structure-preserving simulations of three magnetohydrodynamics models reveal divergent cascade mechanisms and vorticity dynamics despite shared Hamiltonian geometry.
