Vorticity is a vector field variable which is derived from the velocity vector. Mathematically, it is defined as the curl of the velocity vector
In tensor notation, vorticity is given by
where is the alternating tensor. The components of vorticity in Cartesian coordinates are
This can be obtained by using determinants
where are the unit vectors for the Cartesian coordinate system.
Physical Significance
The vorticity can be seen as a vector having magnitude equal to the maximum "circulation" at each point and to be oriented perpendicularly to this plane of circulation for each point.
