Potential VW Sub-Project: Lamb Vector and its Divergence functionObject.
Lamb vector is the cross-product of vorticity and velocity.
The motivation to do so stems from the close connection between the Lamb vector divergence and the motions in a flow, especially those instantaneous motions in turbulent flows, having a distinctively high capacity to effect a time rate of change of momentum, and generate forces such as drag.
