Abstract

Data obtained from direct numerical simulation of the Navier-Stokes equations have shown a tendency for the vorticity vector to align itself in the direction of the intermediate rate of strain. This result was first observed by Ashurst et al. (1987) and later by Jiminez et al. (1993) and Ooi et al. (1994). In this paper, the Reynolds number dependance of the alignment of vorticity with the three principal strain directions is discussed.
