Abstract
Aerodynamics principles play a fundamental role in both energy generation and consumption. Automobile aerodynamics contribute to its overall performance as well as to its efficiency. The purpose of this paper is to provide an overview of some of the available literature on spoilers and vortex generators (VGs). The paper then discusses the impact of the different types of air spoilers and VGs on the Audi R8 2014 vehicle using ANSYS Fluent 19.2. The vehicle has been modified to accommodate simulation using computational fluid dynamics (CFD). The simulation process is briefly described. There have been various spoilers proposed, including pedestal spoilers, trunk spoilers, and wavy spoilers. Additionally, VGs have been proposed, including Gothic, airtap, and B2 spirit VGs. According to simulation results, the trunk spoiler is the most effective among the proposed spoilers, and the Gothic VG is the most effective among the VGs. Consequently, a combination of a trunk spoiler and a Gothic VG has been tested. This results in a 27.7% reduction in lift coefficient and a 16.45% reduction in drag coefficient.
