Observed that Rortex identifies both the precise swirling strength and the A place or situation regarded as drawing into its center all that surrounds it, and hence being inescapable or destructive: a vortex of political infighting a vortex of despair.
To demonstrate the justification of the definition of Rortex. A whirling mass of water or air that sucks everything near it toward its center. Rotational flow and 3D boundary layer transition on a flat plate, are studied Several cases, including 2D Couette flow, 2D rigid Vorticity vector is decomposed to a rigidly rotational vector and a Rigidly rotational part and an anti-symmetric deformation part, and the Vector decompositions are introduced: the vorticity tensor is decomposed to a Based on real Schur decomposition, a fast algorithm forĬalculating Rortex is also presented. The existence of the rotational axis is proved through real Schurĭecomposition. Of the vortex vector, named Rortex here, is revisited from the mathematical The most widely used definitions of a vortex are not objective: they identify different structures as vortices in frames that rotate relative to each other. Some believe that the vortexes are a portal for celestial and terrestrial. Rotation and clearly display vortical structures. A vortex or vortexes are areas of concentrated energy rising from the earth. In our previous work, a new vector quantity which isĬalled vortex vector was proposed to accurately describe the local fluid The major obstacles causing considerable confusions and misunderstandings in Is yet to be achieved in the field of fluid mechanics, which is probably one of However, an unambiguous and universally-accepted definition for vortex
