Rapid distortion of turbulent structures
Abstract
A simple two scale rapid distortion model of turbulence is used to investigate the generation of coherent structures and to explain some dynamical effects (vorticity alignment with the intermediate eigenvector of the rate of strain, and vorticity production) which have been observed in recent Direct Numerical Simulations (Vincent & Meneguzzi 1991, Ashurstet al. 1987).A three dimensional homogeneous, isotropic, turbulent velocity field with the …
