ABSTRACT
A good performance of the heat exchanger will support energy efficiency and economic sustainability. One way to improve heat transfer coefficient is to increase turbulent flow by using vortex generators. The addition of vortex generators on heat exchanger will pose wake on the flow field which then reduce the stability of thermal boundary layer and enhance heat transfer coefficient. The effect of winglet vortex generators with the variations of angle of attack (AoA) is studied in this research. Each variation is applied in a single row and three rows of inline configurations. The results show that the addition of vortex generators with 160o angle of attack and three rows of inline configuration improve heat transfer coefficient as 59% higher than conventional configurations.
