Abstracts: Generally, 35-40% of the heat exchangers used in industries are shell and tube heat exchanger. We had conducted a project in a heat exchanger manufacturing company. There are problems like scaling, fouling, welding defects and maintenance cost. In this project we had completed the design of shell and tube type heat exchanger. Considering this design as the basis we had fabricated the model of shell and tube type heat exchanger. Performance in terms of heat transfer was firstly measured for normal flat baffle having 3:2 cutting ratio. Then after the performance in terms of heat transfer was measured for helical baffle. After measuring the performance for both the types of baffle we compared the results of both the experiments. Also the turbulence gained due to helical baffle helps to reduce the fouling effect in the heat exchanger.
