Abstract

A simulation of a bus model dimensions 200 x 50 x 50 mm was conduc~ using CFD software FLUENT 6.2, in order to investigate the flow around a bus with active drag reduction system. Simulations were carried out for the base model which is the refrence point and two other spoiler models A & B. All models were designed using CATIA & GAMBIT, simulations were carried out for different spoiler angles. The spoiler model B proved to be most efective in reducing drag when the angle of the spoiler is 15°. The spoiler model managed to minimize the drag force by 27 %. The active drag reduction system utilized is a spoiler which change angle at different speed (from 0 to 20 m/s angle the spoiler is 5°, and from 20 to 45 m/s angle of the spoiler is !5°). ii
