Abstract—Among several flow induced vibration mechanisms, fluid elastic instability can cause a fretting wear of tubes of heat exchanger in a short time. For plain tube array of heat exchanger much research is carried out but for finned tube arrays very less work is carried out by considering different parameters. Effect of different parameters of finned tube array on fluid elastic instability, also concept of effective diameter and Connor’s equation are described in this work. This paper reviews theoretical analysis of fluid elastic instability in finned tube array and review on work carried out by different researchers in fluid elastic instability. Lastly the scope to find out effect of various parameter of finned tube array on a fluid elastic instability are clearly described.

Index Terms—Connors equation, Effective diameter, Finned tube, Fluid elastic instability.
