- Description
- Double pipe Heat exchangers are some of the important equipment which is seen in a variety of industrial applications. In the current study a new type of insert, namely Para-Winglet Tape inserts are investigated for thermal and flow behavior from Reynolds number 6000 to 30000. The Para-Winglet Tape inserts are investigated for three sets of pitches and para-inclinations. The inclusion of para-winglet tape on the tube has intensified the turbulent kinetic energy and has resulted in recirculation in-between the inserts. The arrangement of the para-winglet tape has proved their worthiness over the plain tube. The highest Nusselt number was obtained for Case9 at Reynolds number 30000 with an enhancement of 407% and the least was obtained by Case7 at Reynolds number 6000 with an enhancement of 88% compared to plain double pipe heat exchanger. The highest friction factor was obtained for Case3 at Reynolds number 30000 with an enhancement of 846% and the least was obtained by Case7 at Reynolds number 24000 with an enhancement of 286% compared to plain double pipe heat exchanger. The maximum and minium performance optimization index value of 2.69 and 1.09 was achieved for Case9 and Case1 at Reynolds number 30000 and 6000. 2020 The Author(s).
