High Quality Content by WIKIPEDIA articles! In fluid dynamics, vortex stretching is the lengthening of vortices in three-dimensional fluid flow, associated with a corresponding increase of the component of vorticity in the stretching direction due to the conservation of angular momentum.Vortex stretching is at the core of the description of the turbulence energy cascade from the large scales to the small scales in turbulence. In general, in turbulence fluid elements are more lengthened than squeezed, on average. In the end, this results in more vortex stretching than vortex squeezing. For incompressible flow due to volume conservation of fluid elements the lengthening implies thinning of the fluid elements in the directions perpendicular to the stretching direction.
