these data files are closed related to the structural integrity of the tube bundles of heat exchangers such as shell-and-tube heat exchangers and nuclear steam generators. Considering that the vibration of tube bundles caused by unsteady fluid forces in heat exchangers has a big threat of tube integrity, in order to better understand the fluid-elastic instability phenomenon of flow-induced vibrations, we conducted numerical simulations in normal triangular tube arrays to investigate fluid force characteristics and coupling effects on tubes.
