摘要: Turbulence in helium II takes the form of a disordered tangle quantised vortex line. The existing equation dynamics used by Schwarz and others to model evolution does not distinguish between large scale normal fluid velocity local variation introduced presence lines. We derive new which allows be determined modified Navier–Stokes equation. Together, two equations self-consistent determine coupled vortices.
