Abstract
Numerical simulations of the Navier-Stokes equations allow us to investigate the three-dimensional field of the fluid motion at R λ ≤ 200, where R λ is the Reynolds number based on the Taylor microscale λ. It is observed in many DNSs that the region of the high amplitude vorticity has filament-like structures and the details of the geometry of the vortex filaments has been investigated (e.g., [3, 2]). The average radius of the cross section 〈R〉 is observed to be 3 ~ 6η, where η is the Kolmogorov dissipation scale.
