摘要：In th.s.paper a s.mplified approach.to optimize th. des.gn of s.ell Tube h.at Exch.nger [s.h.] by flow induced vibration analys.s.[FVA] is.pres.nted. Th. vibration analys.s.of s.h. h.lps.in ach.eving optimization in des.gn by prevention of tube failure caus.d due to flow induced vibration. Th. main reas.n for tube failure due to flow induced vibration is.increas.d s.ze of s.h.. It is.found th.t in cas. of increas.d s.ze of s.h., th. s.rface area and number of tubes.increas.s. th.s.th. unders.anding and analys.s.of vibration becomes.a very difficult tas.. Again it is.found th.t flow induced vibration analys.s.is.cons.dered as.an integral part of mech.nical & th.rmal des.gn of s.h.. Th. detailed des.gn, fabrication, tes.ing and analys.s.work was.carried out at Alfa Laval (India), Ltd., Pune-10.
