| Summary: | Rear spoiler is a device commonly found on road vehicles for
improving their aerodynamic performance. The main aim of
the present study was to investigate the effect of varying the
spoiler angle on the aerodynamic performance of hatchback
vehicles. A simplified road vehicle model was used to
facilitate the investigation. The study utilized a RANS-based
computational fluid dynamics (CFD) method. As for the
purpose of validating the method, the numerically obtained
results was compared to the experimental data. The numerical result shows that at positive spoiler angle, the aerodynamic lift of the hatchback model has reduced dramatically – up to 2937%. However, the spoiler effect is unfavorable to lift reduction when configured at negative inclination angle. Although the aerodynamic lift was found to decrease with the increase in spoiler angle, there is accompanied by a drag penalty. Finally, the physical mechanism was discussed based on flow visualization results. |
