Local Near-Beltrami Structure and Depletion of the Nonlinearity in the 3D Navier–Stokes Flows

Computational simulations of turbulent flows indicate that the regions of low dissipation/enstrophy production feature high degree of local alignment between the velocity and the vorticity, i.e., the flow is locally near-Beltrami. Hence one could envision a geometric scenario in which the persistenc...
