Improvement of Porsche Cayenne Aerodynamics using Reverse Engineering, CAE and Rapid Prototyping

Abstract

The external vehicle aerodynamics have a strong impact on the vehicle’s fuel efficiency and handling behavior. External aerodynamic simulations using computational fluid dynamics (CFD) have been used in the automotive industry to develop modern cars. This project aims to study the external aerodynamics of a Porsche Cayenne model. The car model is scanned by a 3D laser scanner and the scanned data is used to reconstruct the 3D CAD model by reverse engineering for CFD simulation. The CFD simulation results will be used to develop a new car model shape to improve the aerodynamic performance. The new car model will be prototyped by a 3D printer.
