STUDI EKSPERIMENTASI OPTIMASI FAIRING PADA KENDARAAN TRUK

Abstract

This study aims to determine the effect of changes in drag with the addition of a fairing on the roof of the truck cabin. The various fairing designs used certainly have different effects to determine the optimal fairing design that can reduce the drag coefficient on the truck. The result of this research concludes that the shape of the fairing design has an influence on the magnitude of the drag force that occurs on the truck for the optimal fairing model is the fairing model with the smallest drag coefficient value where the shape of the fairing used is fairing C on the truck, the drag coefficient value generated is that as low as 0.639. For the percentage of decrease in the value of the highest drag coefficient on trucks when using fairing C with an average percentage decrease of 18.54%.
