| Abstract | Among many techniques (both passive and active) investigated for augmentation of heat transfer rates inside circular tubes, a wide range of inserts has been utilized, particularly when turbulent flow is considered. The inserts studied included coil wire inserts, brush inserts, mesh inserts, strip inserts, twisted tape inserts etc. Augmentation of convective heat transfer in internal flows with twisted tape inserts in tubes is a well-acclaimed technique employed in industrial practices. CFD investigations on enhancement of turbulent flow heat transfer with twisted tape inserts in a horizontal tube under forced convection with air flowing inside is carried out using ANSYS FLUNT. The variations of heat transfer coefficients; Nusselt number in the horizontal tube fitted with twisted tape is studied. A CFD investigation is conducted to study forced convection of fully developed turbulent flow through circular tube with twisted tape inserts. CFD solutions are obtained using commercial software ANSYS FLUENT v12.1. The working fluid in all cases is air. |
