管壳式换热器运行中可能出现的一个重要问题是管振动，尤其是随着壳侧流速增加以改善传热和减少污垢的新趋势。不同的流动现象会导致管道振动。这些包括旋涡脱落、湍流抖振、流体弹性旋涡、旋涡形成和声学振动。各种研究人员提出的预测这些流动现象特征频率的方法是基于理想管束中的试验，通常不适用于两相流。这些方法在应用于全尺寸管壳式换热器的复杂问题时变得不确定，需要测量管的应力状态。 本文介绍了一种离心式冷水机组蒸发器管可靠性的评估方法，并叙述了该方法的实际实验应用。引用:研讨会，ASHRAE交易，第83卷，第2部分，哈利法克斯，北卡罗来纳州

An important problem that may arise in the operation of tube and shell heat exchangers is tube vibrations, especially with the new trend toward increasing shellside flow velocities to improve heat transfer and reduce fouling. Different flow phenomena can cause tubes to vibrate. These include vortex shedding, turbulent buffeting, fluidelastic whirling, eddy formation, and acoustic vibration. The predictive methods proposed by various investigators for the characteristic frequencies of these flow phenomena are based on tests in ideal tube banks, and they are usually not applicable to 2-phase flow. These methods when applied to the complex problem of the full-size shell-and-tube exchanger become uncertain, and a measurement of the stress state of the tubes is desirable.This paper describes a method for assessing the reliability of tubes in the evaporator of a centrifugal water chiller and relates an actual experimental application of the proposed method.
