Abstract

An automotive radiator is a device that helps to prevent over heat of the engine and also to help maintain optimal working temperature of the engine. There are many ways to further enhance the radiator heat dissipation performance so that the radiator can dissipate heat more effectively. This research is a further work from Ying Huang et.al, 2017 that they had conducted a comparative study between flat tube type radiating tube and their proposed wasp-waisted tube type radiating tube and found out the wasp-waisted tube have a better heat dissipation performance. This research was to continue Ying Huang’s work to investigate and find the optimal waist angle of wasp-waisted tube type radiating tube in terms of heat transfer and pressure drop. The study was conducted numerically through ANSYS Fluent simulation software. This study compares the heat transfer and pressure drop performance of different waist angles for the wasp-waisted tube type radiating tube to deduct the optimal angle for heat transfer and pressure drop. The optimal waist angle for heat transfer and pressure drop was deduced in this study. The overall optimal waist angle that caters to both heat transfer and pressure drop was also deduced in this study.
