The aerodynamic development of road car have been progressing as engineering tools become more accurate and feasible. Wind tunnels more similar to the real environment, as well as computational techniques with improved modelling and hardware, lead the development of aerodynamic applications to focus on details.
In this scenario, exhaust gases may jump from ordinary residuals to useful flow for aerodynamic control.
The objective of this paper is to investigate the effect of exhaust tailpipe position on drag coefficient over a 3D realistic road car model.
Therefore, the main contributions of this paper are (i) to present the influence of tailpipe position over the car, as well as (ii) to provide results that may support technical decision concerning performance and design targets on a road car project.
