【 摘 要 】

In This project deals with the utilization of various twisted tape inserts as Passive Heat transfer improvement device. result of twisted tape insert (TTI), Baffled twisted tape insert (BTTI) & Baffled twisted tape with holes insert (BTTHI) on heat transfer and friction factor for heating of water for Reynolds range vary 2600-32000, was studied through an experiment during a double pipe heat exchanger. Three tapes of various twist magnitude relation (TR=3.60, TR=4.30, TR=5.20) for TTI, BTTI & BTTHI were used. The parameter which we a re calculating in this is heat transfer coefficient and friction factor.
