    Abstract :

    Shell and tube heat exchangers are used extensively throughout the process industry. Vibration of tubes in heat exchangers is an important limiting factor in heat exchanger operation. One of the design specification on which vibration is dependent is the unsupported tube length which is a function of baffle spacing. In this paper, the vibration analysis for the shell and tube heat exchanger is carried out at different values of baffle spacing using CHEMCAD. The change in the values of various vibration mechanisms is noted by changing the baffle spacing of a shell with single segmental baffles at 0.072m, 0.076m and 0.08m. The changes in the cross-flow velocity, critical velocity, natural frequency, vortex shedding frequency and turbulent buffeting frequency throughout the length of tube of the heat exchanger are studied.
