Vorticity: dynamics of vortices

2001
Abstract In the discussion (Section 3.2) of deformations of an element of fluid, we have seen the appearance of a term involving the local rotation-the antisymmetric part of the velocity gradient tensor. The corresponding local rotation vector equals half the vorticity vector, defined as the curl of the velocity field. Thus, vorticity

Streamlines, vorticity lines, and vortices

29th Aerospace Sciences Meeting, 1991
The properties of vortical flows are studied using both theoretical analysis and computational flow fields. The consequences of two definitions of the vortex core, a minimum in the streamline curvature and a maximum in the normalized helicity, are examined.

Concentration of vorticity and helical vortices

Fluid Dynamics, 1983
The concentration of vorticity and dynamics of vortices in the field of a helical vortex have been studied for a plane flow of incompressible inviscid fluid. The process of formation of concentrated vortices in the case of a sink and an axisymmetric vorticity field has been considered.

Vorticity, Potential Vorticity

1992
This lecture recalls the basic properties of vorticity and provides a summary of the main conservation laws associated with vorticity and its related quantities. It will be stated as clearly as possible how these different properties are used in industrial situations and in geophysical flows.
