Heat exchangers are very important heat and mass exchange apparatus in various process industries. Among all types of the heat exchanger shell and tube heat exchangers are commonly and effectively used in industries or applications. Heat exchanger performance can be improved by using various augmentation techniques. Generally in shell and tube heat exchanger segmental baffles are used. The purpose of baffle is to guide the flow and support for tubes. In this study the performance improvement of heat exchanger is done using slotted baffle instead of segmented baffle as segmental baffle have problems like flow induced vibrations etc. Present study aims at developing a heat exchanger model with slotted baffle and comparing the results experimentally with the heat exchanger having segmental baffle.
