摘要: 流体横掠单管或管束时产生所谓诱导振动。这种诱导振动常常是引起热交换器损坏的主 要原困之一。P。idous幻s’“综述了由于流动所引起的诱导振动而导致热交换器损坏的50多种 情况。由仕可看出对诱导振动研究的必婴什。

Abstract: Gas-liquid flow-induced vibration in heat exchangers was studied experimentally with a working substance R12 at a pressure(10-14) × 105Pa. The amplitudes of flow-induced vibrations of heat exchanger tube parallel to and perpendicular to the flow in one-phase and in two-phase were measured. The effects of pressure, gas holdup, mass flux, etc. on flow-induced vibration were shown in detail.
