摘要

Radiator tube thermal performance for mixed convection was analyzed by varying their geometrical parameters. Geometrical parameters, such as the inclination of the tubes along different axes, were used for the analysis. This study employs a computational model with varying boundary conditions and forced convection airflow across the tubes. The thermal analysis explores the effects of altering the shapes and inclinations of the tubes at various angles, specifically 2, 3, 4, 5, and 6 degrees relative to the tube’s profile. The authors believe that the two-axis orientation of radiator tube geometry was previously unexplored by other researchers; hence, different degrees of tube orientation have been explored in the current work. The research presents heat transfer variations for radiator tubes with and without inclination, using graphs and contour projections. It is observed in the analysis that the Nusselt number for 23 inclined axis combination of the tubes is the highest. The study demonstrates that, the pressure losses increase with the surge in angle of inclination, and for low angle of inclination, it is minimum. The results display that the vent coolant temperature is reduced by two degrees as compared to straight tubes and full tube. These findings can be applied to any system requiring additional cooling without additional effort.
