초록

In this study, a numerical approach for automotive louvered fin heat exchanger is carried out to investigate the effect of louvered angle on the heat transfer characteristics. The numerical simulation code STAR-CCM+ is utilized to calculate flow and temperature fields with polyhedral meshes. The results show that the flow efficiency is increased as the louver angle is high. Also, the outlet temperatures are nearly the same according to louver angles because the average Nusselt numbers are nearly equivalent regardless of louver angle.
