Dynamics of vortical structures in a homogeneous shear flow. (English) Zbl 0814.76049
The mechanism of generation, development and interaction of vortical structures, extracted as concentrated-vorticity regions, in homogeneous shear turbulence is investigated by the use of the results of a direct numerical simulation of the Navier-Stokes equations with $$128^ 3$$ grid points. Among others, a few of typical interacting vortical structures are identified as important dynamical elements, namely longitudinal and lateral vortex tubes and vortex layers.
