摘要：In this paper a simplified approach to optimize the design of Shell Tube Heat Exchanger [STHE] by flow induced v.bration analysis [Fv.] is presented. The v.bration analysis of STHE helps in achiev.ng optimization in design by prev.ntion of tube failure caused due to flow induced v.bration. The main reason for tube failure due to flow induced v.bration is increased size of STHE. It is found that in case of increased size of STHE, the surface area and number of tubes increases, thus the understanding and analysis of v.bration becomes a v.ry difficult task. Again it is found that flow induced v.bration analysis is considered as an integral part of mechanical & thermal design of STHE. The detailed design, fabrication, testing and analysis work was carried out at Alfa Lav.l (India), Ltd., Pune-10.
