In last two decades many technical, experimental and numerical models are being presented on shell and tube heat exchanger by many researchers. In industries shell and tube heat exchangers are used for different applications e.g. for waste heat recovery, oil refineries etc. This paper focus on the experimental investigation of shell and tube heat exchanger with different type of baffles. The shell and tube heat exchanger with segmental baffles and flower baffles are designed, fabricated and tested. The thermal and hydraulic performance of both heat exchangers are compared with same operating conditions. The heat exchanger with flower baffle gives more efficient overall performance up to 25-32% than segmental baffles heat exchanger. Also the pressure drop gets reduced in flower baffle heat exchanger up to 20-28% than segmental baffles heat exchanger.
