摘要： A conduit for carrying fluid in a downstream direction includes a diffusing section. Downstream extending convolutions in the wall of a diffusing section energize the boundary layer and delay boundary layer separation from the wall surface of the diffusing section or permit an increase in the diffusion angle without the occurrence of separation. Such convolutions are particularly useful when rapid diffusion is required in a short distance, such as in the diffusing section of automotive catalytic converter systems. Such a system carries engine exhaust products from a small, cylindrical pipe into a typically larger elliptical cross-section catalyst filled portion. The convolutions help to more uniformly disperse the exhaust gas throughout the catalyst bed using a relatively short diffusion section.
摘要翻译：用于在下游方向承载流体的导管包括扩散部。在扩散部分壁的下游延伸的卷积使边界层激励边界层，并且延伸边界层与扩散部分的壁表面分离，或允许扩散角增加而不发生分离。当在短距离内需要快速扩散时，例如在汽车催化转化器系统的扩散部分中，这种卷积特别有用。这种系统将发动机排气产品从小的圆柱形管道运送到通常较大的椭圆形截面催化剂填充部分。卷积有助于使用较短的扩散部分将废气更均匀地分散在整个催化剂床中。

摘要： A thin, convoluted wall member disposed upstream of the inlet of a diffuser generates large-scale vortices having axes in the downstream direction. The vortices enhance mixing within the diffuser and can also energize the boundary layer, thereby improving diffuser performance and delaying the onset of stall. Greater diffusion angles without stall are possible. The member itself creates low losses.

摘要： An airfoil has a plurality of spaced apart, U-shaped troughs in either or both its suction or pressure surface in the trailing edge region. Each trough extends in a direction generally parallel to the bulk fluid flow in its vicinity near the airfoil surface and has an outlet at the trailing edge. The troughs increase in depth from their inlets toward their outlets, the maximum depth being no more than half the trailing edge thickness. The troughs are spaced apart, sized and configured to flow full over their entire length and to cause fluid to flow into the space immediately behind the trailing edge, thereby reducing base drag.

摘要： To reduce noise, an automotive exhaust tailpipe has a convoluted surface at or near its outlet to generate pairs of counterrotating axial vortices within the exhaust gases just before or just as the gases exit the tailpipe. The convoluted surface may be the internal surface of the tailpipe, or a thin-walled convoluted member may be disposed within the tailpipe near its outlet end.

摘要： A fluid dynamic pump, such as an ejector, has a common wall which separates a primary high energy fluid flow passage and a secondary low-energy fluid flow passage. The common wall includes a plurality of adjoining lobes extending in the direction of flow to the outlets of the passages at the downstream end of the common wall. A lobe on one side of the wall forms a corresponding trough on the other side. The common wall therefore has a wave-like shape at its downstream end. Primary and secondary fluid flow from the trough outlets on their respective sides of the common wall and are mixed together rapidly in a mixing region downstream of the outlets. A diffuser is located at the downstream end of the mixing region and enhances the pumping ability of the ejector. Secondary fluid is thereby drawn or pumped into the mixing region as a result of this transfer of energy from the primary stream to the secondary stream. Viscous losses are low during the process.
摘要翻译：诸如喷射器的流体动力泵具有分开初级高能流体流动通道和次级低能流体流动通道的公共壁。公共壁包括沿公共壁的下游端在通道的出口方向上延伸的多个相邻的叶片。墙的一侧的叶片在另一侧形成相应的槽。因此，普通壁在其下游端具有波状形状。初级和次级流体从公共壁的相应侧面上的槽出口流出并且在出口下游的混合区域中快速混合在一起。扩散器位于混合区域的下游端，并提高喷射器的泵送能力。因此，由于将能量从初级流转移到次级流中，二次流体被抽吸或泵入混合区域。此过程中粘性损失较低。

摘要： In a heat exchanger, a convoluted plate disposed in a fluid stream flowing in an axial direction generates adjacent counterrotating, large scale axial vortices downstream thereof adjacent a wall over which the fluid flows. The convoluted plate is constructed to produce minimum pressure losses, while the vortices increase the heat transfer rate between the fluid and the wall.

摘要： A projectile having a downstream extending surface of revolution which terminates as a blunt base has a plurality of circumferentially spaced apart U-shaped, downstream extending troughs in its surface. Each trough is essentially aligned with the direction of the bulk fluid flow adjacent the surface in the vicinity of the trough, and intersects the blunt base to form a trough outlet therein. The troughs are appropriately spaced apart, sized and configured to flow full over their entire length and to cause fluid to flow into the space immediately behind the blunt base, thereby reducing base drag on the projectile.

摘要： An airfoil-shaped body has a relatively thin trailing edge with a series of alternating, adjoining, downstream extending troughs and ridges in its suction surface which form wave-like surface undulations terminating at the trailing edge. The ridges in the suction surface form corresponding troughs in the pressure surface near the trailing edge; and the troughs in the suction surface form corresponding ridges near the trailing edge of the pressure surface. The resulting airfoil-shaped body has a trailing edge with a wave-like shape. The trough and ridge construction delays or prevents two-dimensional boundary layer separation without creating an undesirable drag penalty.

摘要： A body adapted to move downstream through a fluid has a downstream extending smooth surface terminating at a blunt base. A plurality of adjacent U-shaped, downstream extending troughs in the smooth surface intersect the blunt base to form trough outlets. The troughs are appropriately spaced apart, sized and configured to flow full over their entire length and cause fluid to flow into the space immediately behind the blunt base, thereby reducing base drag on the body.
