Title: Dynamic Phase Alignment in Navier-Stokes Turbulence

Journal Article · · Physical Review Letters

In Navier-Stokes turbulence, energy and helicity injected at large scales are subject to a joint direct cascade, with both quantities exhibiting a spectral scaling ∝k-5/3. We demonstrate via direct numerical simulations that the two cascades are compatible due to the existence of a strong scale-dependent phase alignment between velocity and vorticity fluctuations, with the phase alignment angle scaling as cosαk∝k-1.
