Unformatted text preview: 2. A solid-body rotation (rigid-body rotation) flow is rotational ( Î¶ G â‰ 0). In fact, since vorticity is equal to twice the angular velocity, 2 Ï‰ = G G everywhere in the flow field . Fluid particles rotate as they revolve around the center of the flow. This is analogous to a merry-go-round or a roundabout. G Solid-body rotation 3. A line vortex flow, however, is irrotational ( = 0), and fluid particles do not rotate, even though they revolve around the center of the flow. This is analogous to a Ferris wheel. Line vortex See text for details and calculations....
