Abstract

 In present day shell and tube heat exchanger is the most common type heat exchanger widel y used in oil
refinery and other large chemical process, because it suits high pressure application. An attempt made to decrease the
pressure drop and to increase the heat transfer and the ratio of heat transfer and pressure drop in shell and tube type
heat exchanger by varying the baffle angle up to which we get the minimum pressure drop. It analyzes the conventional
segmental baffle heat exchanger using the Kern’s method with fixed shell side flow rates and varied volume flow rate.
Since Kern’ method used in design of heat exchangers with a baffle cut of 25% (fixed). The thermal analysis of helical
baffle heat exchanger using this method give us clear idea that the ratio of heat transfer coefficient per unit pressure
drop is maximum in helical baffle heat exchanger as compared to segmental baffle heat exchanger
