Vortex Stretching Technology Peer Review Journal

In fluid dynamics, vortex stretching is that the lengthening of vortices in three-dimensional fluid flow, related to a corresponding increase of the component of vorticity within the stretching direction—due to the conservation of momentum. Vortex stretching is at the core of the outline of the turbulence energy cascade from the massive scales to the tiny scales in turbulence. Generally, in turbulence fluid elements are more lengthened than squeezed, on the average. Within the end, this leads to more vortex stretching than vortex squeezing. For incompressible flow—due to volume conservation of fluid elements—the lengthening implies thinning of the fluid elements within the directions perpendicular to the stretching direction. This reduces the radial length scale of the associated vorticity. Finally, at the tiny scales of the order of the Kolmogorov microscales, the turbulence K.E. is dissipated into heat through the action of molecular viscosity. Peer-reviewed (refereed or scholarly) journals - Articles are written by experts and are reviewed by several other experts within the field before the article is published within the journal so as to make sure the article’s quality. (The article is more likely to be scientifically valid, reach reasonable conclusions, etc.) In most cases the reviewers don't know who the author of the article is, in order that the article succeeds or fails on its own merit, not the reputation of the expert.
