New discovery upends an 80-year-old theory of turbulence | ScienceDaily

Scientists just broke an 80-year-old law of fluid physics — by running turbulent energy backwards, upending the Kolmogorov cascade theory that underpins everything from weather models to jet engines.

Theory Briefing

  • Researchers reversed the direction of energy flow in turbulence, a feat deemed impossible under Kolmogorov's 1941 cascade theory.
  • The Kolmogorov energy cascade assumes energy always flows from large to small scales — this experiment proves that flow can be flipped.
  • Overturning this 80-year-old framework could reshape how scientists model weather, ocean currents, and aerodynamic systems.
