Heat exchangers are devices used to transfer heat between two or more fluid streams at different temperatures. A very serious problem in the mechanical design of heat exchangers is flow induced vibration of the tubes. There are several possible consequences of tube vibration, all of them bad. The tubes may vibrate against the baffles, which can eventually cut holes in the tubes. In extreme cases, the tubes can strike adjacent tubes, literally knocking holes in each other. The repeated stressing of the tube near a rigid support such as a tube sheet can result in fatigue cracking of a tube, loosening of the tube joint and accelerated corrosion. The flow induced vibrational analysis is considered as integral part of mechanical and thermal design of shell and tube heat exchangers. TEMA has developed standards in areas of flow induced vibrational analysis which have achieved worldwide acceptance. The paper explains depth vibrational analysis of a real world project in accordance to TEMA regulations.
