Due to design limitations or system upgrade, heat exchangers are required to operate in the laminar-to-turbulent transition region in order to achieve a high heat transfer with low pressure drop. The present research investigates the effect of vertical upflow with heating on the single-phase heat transfer in the transitional flow regime of a vertical tube. The experimental setup consists of a swinging test bench which allows for horizontal flow and vertical upflow direction under constant heat flux boundary condition. A smooth circular tube with inner diameter of 5.1 mm and a heated length of 4.52 m was used as the test section with water at Prandtl number ranging between 5 to 7 as working fluid. The experiment covers Reynolds nu...
