Abstract
The main aim of this thesis is to compare and improve the various heat transfer parameters like overall heat transfer coefficient and heat transfer in double pipe heat exchanger for four different cases, i.e. Plain tube, Corrugated tube, Plain tube with helically twisted wire and Plain tube with twisted clip . The above work is done experimentally on concentric tube heat exchanger. This works falls under Passive techniques, where inserts are used in the flow passage to augment the heat transfer rate, are advantageous compared with active techniques, because the insert manufacturing process is simple and these techniques can be easily employed in an existing heat exchanger. The data obtained from experiment were used calculating the various parameters as discussed.
