Vorticity is positive when – looking down onto the earth's surface – the wind turns counterclockwise. In the northern hemisphere, positive vorticity is called cyclonic rotation, and negative vorticity is anticyclonic rotation; the nomenclature is reversed in the Southern Hemisphere. See more In continuum mechanics, vorticity is a pseudovector field that describes the local spinning motion of a continuum near some point (the tendency of something to rotate ), as would be seen by an observer located at that point and … See more In a mass of continuum that is rotating like a rigid body, the vorticity is twice the angular velocity vector of that rotation. This is the case, for example, in the central core of a See more The evolution of the vorticity field in time is described by the vorticity equation, which can be derived from the Navier–Stokes equations. In many real flows where the viscosity can be neglected (more precisely, in flows with high See more Rotating-vane vorticity meter A rotating-vane vorticity meter was invented by Russian hydraulic engineer A. Ya. Milovich … See more Mathematically, the vorticity of a three-dimensional flow is a pseudovector field, usually denoted by $${\displaystyle {\vec {\omega }}}$$, defined as the curl of the velocity field $${\displaystyle {\vec {v}}}$$ describing the continuum motion. In Cartesian coordinates See more A vortex line or vorticity line is a line which is everywhere tangent to the local vorticity vector. Vortex lines are defined by the relation See more Aeronautics In aerodynamics, the lift distribution over a finite wing may be approximated by assuming that each spanwise segment of the wing has a semi … See more WebWe study the stripping of vortices with monotonic vorticity profiles within adverse shear. It is shown that distributed vortices behave differently from uniform patches regarding the …

In early days, since Helmholtz’ definition of vorticity tube/filament dated 1858, people have in general believed that vortices consist of small vorticity tubes and the vortex strength is represented by the magnitude of the vorticity, which is a mathematical definition of the velocity curl, i.e., \(\overrightarrow{\omega … john b watson 1878 to 1958 behaviorism
