Design Optimization of Shell and Tube Heat Exchanger by Vibration Analysis

“…The characteristics of vortex shedding from tube banks with closely mounted serrated fin was investigated in [1] where the relationship between the Strouhal number defined by the equivalent diameter as the characteristic length of a finned tube in the tube banks and the Strouhal number map for bare-tube banks was examined. Whereas in [2] the author has presented various outlet conditions of a shell and tube heat exchanger theoretically and experimentally in which it is observed that prime parameter geometry of outlet affects the performance, maintenance and life span of a vertical shell and tube evaporator. The heat transfer enhancement has been achieved in [3], by modifying the configuration of a shell-and-tube heat ex-changer, through the installation of sealers in the shellside.…”

“…In this proposed work design, development & testing of STHE is carried out. Along with the parameter considered in [1][2][3][4][5][6][7][8], vibration analysis is performed to optimized unsupported span of tube by using HTRI software. Detail overview on work carried out by researchers is presented in Section 1, Section 2 & 3 states mechanics of flow-induced vibration and the current problem definition & objective, details of STHE is given in Section 4.…”
