In [[fluid dynamics]], '''turbulence''' or '''turbulent flow''' is fluid motion characterized by [[Chaos theory|chaotic]] changes in [[pressure]] and [[flow velocity]]. It is in contrast to a [[laminar flow]], which occurs when a fluid flows in parallel layers, with no disruption between those layers.<ref name=Batchelor>{{cite book | last=Batchelor | first=G. | title=Introduction to Fluid Mechanics | year=2000}}</ref>

在流体力学中，湍流或紊流是以压力和流速的混乱变化为特征的流体运动。相反，层流是指流体在无互相干扰和中断的平行层中流动。
