流线型 Streamlines, streaklines, and pathlines

（重定向自Stream line）
流线型与模拟的层流
The red particle moves in a flowing fluid; its pathline is traced in red; the tip of the trail of blue ink released from the origin follows the particle, but unlike the static pathline (which records the earlier motion of the dot), ink released after the red dot departs continues to move up with the flow. (This is a streakline.) The dashed lines represent contours of the velocity field (streamlines), showing the motion of the whole field at the same time. (See high resolution version.)
A long exposure photo of sparks from a campfire shows the pathlines for the flow of hot air.

流线型是物体的一种外部形状，通常表现为平滑而规则的表面、没有大的起伏和尖锐的棱角。流体在流线型物体表面主要表现为层流，没有或很少有湍流，这保证了物体受到较小的阻力。流线型物体通常较为美观，经常出现在产品外观设计中。 流线，用来表征三维空间的速度场。在当流场随着时间改变的时候，即非稳定流动时，Streamlines, streaklines, and pathlines三个名词含义不同。

流线型的起源可以追溯到19世纪对自然生命的研究，以及对于鱼、鸟等有机形态的性能的欣赏。这些最初应用在潜艇和飞艇的设计中，以减少湍流和阻力。于第一次世界大战前后流线型更是用于小汽车的外型设计上。今时今日，汽车、火车、飞机和轮船等交通工具早已采用了流线型的设计。

Example of a streakline used to visualize the flow around a car inside a wind tunnel.

Fluid flow is characterized by a velocity vector field in three-dimensional space, within the framework of continuum mechanics. Streamlines, streaklines and pathlines are field lines resulting from this vector field description of the flow. They differ only when the flow changes with time: that is, when the flow is not steady.
