title = "Numerical investigation of helicity in turbulent flow",
abstract = "Results of direct numerical simulations of decaying, nearly isotropic turbulence are presented. The angular orientation between vorticity and velocity evolves from a state that is initially random to one in which there is a higher probability of vector alignment. Total helicity evolves in a quantitatively different manner than the energy or ensotrophy, reflecting changes of flow topology. From a random, initially zero-helicity field it is seen that viscosity can be a source of spontaneous helicity generation and reflexional symmetry breaking.",
