Efforts have been made to increase thermal efficiency of tube bundle heat exchangers by increasing flow velocities and decreasing tube wall thicknesses, which led to a number of damages due to flow‐induced vibrations. Here, a numerical tool is presented which, for the first time, makes it possible to simulate fluid‐structure‐coupled vibrations in tube bundles in three dimensions. This tool has the potential to optimize tube bundle structures such that thermal efficiency is improved in terms of economy and safety.
