`
`through a rapidly expanding duct—“the reverse of the flow in Fig. 6-la. Here,
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`because of the large and rapid increase of pressure required of the low energy
`
`
`
`
`
`
`
`
`
`
`
`
`
`boundary layer (it has a lower kinetic energy than the main stream), it cannot
`
`
`
`
`
`
`
`
`
`
`
`regain pressure together with the main stream to fill completely the down-
`
`
`
`
`
`
`
`
`
`
`
`
`stream duct. Instead the main flow, while remaining more or less unaffected
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`by viscosity, does not follow the wall but continues into the channel as a jet.
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`The region between the jet and the wall is filled with fluid of lower velocity
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`that churns and eddies in an irregular way. In this way the boundary layer
`
`
`Separation point
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`Separation behind a cylinder. In this particular instance the wake
`Fig. 6-ld
`
`
`
`formed is nonsteady.
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`has brought about a rather severe alteration of the flow picture. When the
`
`
`
`
`
`
`
`
`
`
`
`
`
`‘inain stream (that portion unaffected by Viscosity) does not follow the walls of
`
`
`
`
`
`
`
`
`
`
`
`
`
`3hr: surrounding duct or adjacent solid surface,
`it is said to separate or
`
`
`
`
`
`
`
`
`
`
`
`
`yank-away. A similar situation is observed for the flow around a cylinder
`
`
`
`
`
`
`
`
`
`
`
`
`
`Fig. 6-ld). The main flow separates at a position near the maximum height;
`
`
`
`
`
`
`
`
`
`
`
`
`hind the cylinder there is an eddying wake which extends for many diam-
`
`
`
`
`
`
`
`
`
`
`
`
`bters downstream. On the forward portion of the cylinder a relatively thin
`
`
`
`
`
`
`
`
`
`
`
`:fioundary layer develops (at fairly large Reynolds numbers), and the flow
`
`
`
`
`
`
`
`
`
`
`
`
`
`interior to this and to the wake may be considered to be inviscid.
`
`
`
`
`
`
`
`
`
`
`
`These examples illustrate two features of recurring importance in fluid
`
`
`
`
`
`
`
`
`
`
`
`mechanics: the development of viscous regions and the occurrence of the
`
`
`
`
`
`
`
`
`
`
`hparation phenomenon. Because of the possibility of separation one cannot
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`Ways assume that the inviscid portion of the flow will conform to the shape
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`flsolid boundaries in the flow. In the absence of separation and at sufficiently
`
`
`
`
`
`
`
`
`
`
`
`
`high Reynolds numbers, however, the. actual boundaries may be taken as the
`
`
`
`
`
`
`
`
`
`
`
`
`bonndaries for the inviscid flow, because of the thinness of the boundary
`
`
`
`
`
`
`
`
`
`
`
`
`yer. In general these conditions are fulfilled in the forward portions of
`
`
`
`
`
`
`
`
`
`
`
`"ant bodies or along airfoil-like shapes, particularly in regions where the
`
`
`
`
`
`
`
`name decreases in the direction of flow.
