Numerous works have been carried out by researchers into the physics of heat transfer in pipe flow. The current work aims at the enhancement of heat transfer rate in circular cross-sectioned pipe flow using rotating twisted tape insert. The novelty of this work lies within the employment of rotating twisted pipe insert for obtaining a greater heat transfer rate. An effort is given herewith to observe the effect of varying combination of rotational speed of the twisted tape insert, and volume flow rate of fluid on the overall heat transfer coefficient, heat transfer rate and heat transfer enhancement efficiency of the system. A physical model of the experimental setup was designed, built and instrumented for temperature measurements, which are used for the determination of the different performance characteristics. The volume flow rate of fluid was varied from 8 LPM to 16 LPM and the rotation of twisted tape was varied from 0 RPM to 600 RPM. The effects of relevant parameters experimental setup are investigated.
