A review on the research made by researchers on the finned tubes used in the heat exchangers is done. The aim is to
improve the fluid elastic instability of the tubes used in the heat exchangers to avoid the failure of the tubes due the vibrations
induced because of the fluid flow over the tubes. The fluid elastic instability point varies with various parameters. The
parameters like fin geometries, fin pitch, fin height, fin thickness, fin density on different tube arrays have been reviewed in this
paper. Main motive of the paper is to provide some brief knowledge about instability point of the fin tubes depending on the tube
parameters and tube array.
