The main intenion of the study was to experimentally investigate transfer of heat and drop in pressure increment characteristics in a smooth circular copper tube with peripheral double u-cut twisted tape (PDUCTT) insert in a tube. The PUDCTT inserts is made from 3 mm thick and 25 mm wide copper strips. The tape has peripheral cuts with twistand depth ratio of 1.25 were twisted to obtain a twist ratio of 6 with u-cut on both sides.. This study focussed on the identification of the extreme flow regime with the PUDCTT inserts, Transfer in heat and drop in pressure connection therefore developed to veticinate the experimental data in the laminar, transitional and turbulent flow regimes as relates to Reynolds number, depth ratio.
