阻力 Drag (physics)

(重定向自Wind resistance)
NASA对阻力的解说
三个由相同角度(70°)射出物体的轨迹。黑色物体未受到任何阻力,其轨迹为抛物线,蓝色物体受到斯托克斯阻力,而绿色物体受到牛顿阻力。
诱导阻力和升力的关系
功率曲线:寄生阻力及诱导阻力和速度之间的关系

阻力,又称后曳力流体阻力,是物体在流体中相对运动所产生与运动方向相反的力。阻力的方向和其所在流场的流速方向相反。一般摩擦力不随速度变化而变化,但阻力会随速度而变化。

对于一个在流体中移动的物体,阻力为周围流体对物体施力,在移动方向的反方向上分量的总和。而施力和移动方向垂直的分量一般则视为升力。因此阻力和物体移动方向恰好相反,像飞机前进时会产生推力来克服阻力的影响。

在航天动力学中,大气阻力可以视为太空飞行器在发射时的低效率,其影响则是在发射时需要额外的能量,不过在返回轨道时大气阻力有助于太空飞行器减速,可减少减速额外需要的能量,不过大气阻力产生的热量甚至可以将物体熔化。

Drag (physics) 阻力

(重定向自Wind resistance)
Drag coefficient Cd for a sphere as a function of Reynolds number Re, as obtained from laboratory experiments. The solid line is for a sphere with a smooth surface, while the dashed line is for the case of a rough surface.
Explanation of drag by NASA.
An object falling through viscous medium accelerates quickly towards its terminal speed, approaching gradually as the speed gets nearer to the terminal speed.  Whether the object experiences turbulent or laminar drag changes the characteristic shape of the graph with turbulent flow resulting in a constant acceleration for a larger fraction of its accelerating time.
Trajectories of three objects thrown at the same angle (70°). The black object does not experience any form of drag and moves along a parabola. The blue object experiences Stokes' drag, and the green object Newton drag.

In fluid dynamics, drag (sometimes called air resistance, a type of friction, or fluid resistance, another type of friction or fluid friction) is a force acting opposite to the relative motion of any object moving with respect to a surrounding fluid. This can exist between two fluid layers (or surfaces) or a fluid and a solid surface. Unlike other resistive forces, such as dry friction, which are nearly independent of velocity, drag forces depend on velocity. Drag force is proportional to the velocity for a laminar flow and the squared velocity for a turbulent flow. Even though the ultimate cause of a drag is viscous friction, the turbulent drag is independent of viscosity.
