Abstract

Aerodynamic optimization of automotive vehicles has grown into a major discipline in the realm of modern computational fluid dynamics (CFD). Many different aspects exist to this intriguing area of fluid dynamics including full body streamlining, spoiler performance, wake turbulence, ground-wheel interaction, separation, boundary layer detachment, aero-acoustics and protuberance flow fields. Wing mirrors are an essential peripheral body component in all road vehicles and are known to induce considerable drag effects with interference downstream in the aft region. Porsche automobiles have pioneered the use of wind tunnel testing to produce more efficient geometric designs for wing mirrors. Motivated by exploring the performance of such components, in the present study a detailed laminar and turbulent simulation of the flow field around a Porsche GT3 RS 2016 wing mirror model is conducted. The RANS k-epsilon model is adopted in ANSYS FLUENT version 19.1. Adaptive mesh design is employed. Two-dimensional computations are performed (based on actual measurements taken) and extensive visualization of the pressure and velocity fields in wake path is included for a range of cruising speeds. The analysis reveals some interesting features of unsteady boundary layer characteristics which have been neglected in previous studies and furthermore highlights the excellent facility for exploring complex aerodynamic regimes with computational fluid dynamics technology.
