摘要
围绕吸流管道的稳定性与振动问题,对近年来的主要研究工作加以综述并提出预测,其中包括运动方程的归纳与讨论、管道自由端口处的流固耦合理论、定常流速下吸流管道的稳定性机理以及今后值得进一步研究的某些问题。
Some recent advances on the dynamical model of pipes aspirating fluid are reviewed here. It is endeavoured to show that there exist some unresolved issues in this dynamical model. The pipes aspirating fluid, on a par with, for instance, the dynamical problem of pipes discharging fluid, is capable of displaying much richer dynamical behaviour. The equations of motion, fluid-solid interaction theory at the inlet of the free end of the pipe, and the stability mechanism of pipes aspirating steady fluid are provided. Finally, the promising future development in this field is further discussed.
