中文摘要
翻译
管壳式换热器是许多行业的主力设备,包括电力、石化和流程工业。这些装置包含数千个管子,通过它们的管壁在不同温度的两种流体之间交换热量。热交换器壳侧(管子外)的高速流动产生了大量的动能。如果这种能量只有一小部分被转化为振动,那么管子的结构完整性可能会受到影响。
英文摘要
Tube-and-shell heat exchangers are the workhorse of many industries, including the power, petrochemical, and process industries. These devices contain thousands of tubes and through their walls heat is exchanged between two fluids at different temperatures. Significant amount of kinetic energy arises due to high-speed flow circulating in the shell-side (outside the tubes) of the heat exchanger. The structural integrity of the tubes can be compromised if only a small fraction of this energy is converted into vibrations.
