Numerical investigations of heat transfer and friction factor characteristics in swirling flow conditions using CFD simulation. A commercial CFD package, Ansys R1 2021, was used in this study. 3D models for circular tube fitted with Square-cut twisted tape (QCT) inserts with two pitch 100mm, 50 mm and different cut depths (d = 4 mm, 5mm and 7 mm) were generated for the simulation. Insertion of twisted tapes into the tubes of the heat exchangers is important for enhancement of heat transfer to increase the performance of heat exchangers. In the present Research work, computational analysis has been carried out to analyse the enhancement of rate of heat transfer using Square cut cross sectional twisted tape inserts in a pipe heat exchanger. Geometrical model of heat exchanger has been generated and computational mesh is created using ICEM CFD, an advanced meshing software. The analysis has been carried out for plain tube and with Square cut cross sectional twisted tape inserts with different twist ratio analyse the temperature distribution, velocity distribution and pressure distribution along the tubes and shell using ICEM CFD.
