脉动流是一种特殊的非定常流，其中合成流由平均分量和周期性变化的时变分量组成。振荡流是零平均脉动流的一个分支。脉动流可能出现在一个流动状态：层流，过渡或湍流。在本文中，脉动流的基本术语和关系的基础上发表的理论和实验研究。现有的理论层流和过渡制度的概述。虽然这项研究的主要目的是确定脉动管流的理论，发表的论文相关的流场也进行了审查。
Pulsatile flow is a specific unsteady flow in which the resultant flow is composed of a mean component and a periodically varying time-dependent component. Oscillatory flow is a sub-branch of pulsatile flow with zero mean component. Pulsatile flows may appear in one of the flow regimes: laminar, transitional or turbulent. In this paper, the basic terminology and relationships for pulsatile flows are presented, based on published theoretical and experimental investigations to date. The available theory on laminar and transitional regimes is outlined. Although the primary purpose of the study is to determine the theory of pulsatile pipe flows, published papers on related flow fields are also reviewed.
