Discussion on Flow Induced Vibration Analysis Method for Shell-and-Tube Heat Exchanger with Nuclear Safety Class 2 and 3

Corresponding to the real operation condition of the shell-and-tube heat exchanger with nu-clear safety class 2 and 3,i.e.the water-water heat transfer without phase changing,and according to TEMA standard,the possibility and criteria of the flow induced vibration by vortex shedding,turbulent buffeting,fluid-elastic instability and acoustic vibration are discussed,and the flow induced vibration analysis method for this issue,as well as the solution for the design with the potentially existing dangers of the flow induced vibration damage are presented.
