节流节流Throttled flow节流(throttled flow)节流是强迫流过一个限定面积，在那里流速一定会增加的流动。流过这个收缩区时，由于压力下降而产生的动能通常由于涡旋扰动大部分转换为热能。其结果是这个系统中的机械能损失。例如采用一个球形阀门来节流气体时，阀门下游不远处的速度在大多数情况下只比节流截面前稍大一点。这是一个等烩过程。由于节流阀把机械能损失引入流动系统，而使流量可得到控制。参阅“等嫡过程”(i*n-tropic proeess)条。当气体以声速流过诸如喷管那样的收缩段时，便产生一种特殊的节流效应。此时，进一步降低下游压力不会改变上游状态，同时流量保持常数。 〔斯特里特(v.I砂.Streeter)撰二
