dear junseok kim,
vorticity is precisely defined to be the curl of the velocity vector. it represents the presence or absence of rotation in a flow field. swirl is typically the azimuthal velocity in vortex filament like flow. usually if the swirl is present in a vortex filament (like a tornado), then the vorticity is also present. otherwise thay have no mathematical connection. -vidyadhar mudkavi 30 october 2000 |
