WebAn integral part of fluid dynamics is vorticity. Heuristically, it measures the local rotation of a fluid parcel. For solid objects we do not speak of the vorticity of an object but instead we refer to its angular velocity. These two concepts are related but vorticity is more useful when discussing rotating objects that deform, as a fluid does.
