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.

管壳式换热器是许多行业的主力，包括电力，石化和加工行业。这些装置包含数千个管道，通过它们的壁在不同温度的两种流体之间进行热交换。由于在热交换器的壳程（管外）中循环的高速流，产生大量的动能。 如果只有一小部分能量被转化为振动，管道的结构完整性就会受到损害。
