Abstract

The convective heat transfer coefficient for a uniform heat flux tube is improved experimentally by using a single twisted vanes turbulator. The effect of the twisted vane inserts on the heat transfer rate are studied experimentally. During this study, the operating parameters are Reynolds number (2747 6390), and local position of the swirl} element (S/L=0.0, 0.25, 0.5, 0.75, 1.0). The results demonstrated that the use of twisted vane swirl element inserts leads to a higher heat transfer coefficient rather than that of plain tube and the swirl element p < em>osition of 0.25 from tested tube inlet yields a better heat transfer characteristics. The results are also correlated in the form of Nusselt number as a function of Reynolds number and turbulator position ratio. An augmentation of heat transfer coefficient up to 277% is obtained.
