In modern shell and tube Heat Exchangers (HE), light tubes are used to facilitate the exchange of heat, and to minimize the heat exchanger size. Light tube are more prone to vibration and oscillation when it exposes to cross flow. Tube vibration causes tube damage due to fatigue in long period of time due to turbulent buffeting. Tube failure could be occurred in short time due to FluidEelastic Instability (FEI). In this paper, issues regarding the most Flow-Induced Vibration [FIV] excitation mechanism, which is fluidelastic instability will be presented. The fluidelastic instability criterion are presented in this paper based on numerical and experimental approaches available in the literature. An algorithm that consider the fluidelastic instability while designing shell and tube heat exchanger, is also presented in this paper. Heat transfer model is solved in conjunction with fluidelastic instability model to design shell and tube heat exchanger.
