Nonlocal amplification of intense vorticity in turbulent flows
The nonlinear and nonlocal coupling of vorticity and strain rate constitutes a major hindrance in understanding the self-amplification of velocity gradients in turbulent fluid flows. Utilizing highly resolved direct numerical simulations of isotropic turbulence in periodic domains of up to 12288^{3}...
