Aerodynamics of a 2017 Formula 1 Car: Design Improvements in Freestream and Wake Flows

Abstract

The present publication aspires to be a comprehensive research on the main aspects of open-wheeled racing car aerodynamics. Starting from the comprehension of ground effect principles, the work moves towards the simulation of a modern F1 car. The vehicle aerodynamics is numerically investigated from many points of view: different setups and operating conditions are taken into account in order to fully characterize the behaviour of the vehicle and evidence any possible critical aspects. The considered 2017 F1 car, as expression of current FIA Technical Regulations, has proved to be poorly suited to working in slipstream: as a result, both the approach to a vehicle ahead and the overtaking manoeuvre are difficult and unsafe. In light of this, the core of the research is directed towards the aerodynamic development of the original car, with the aim of improving its performance both in freestream and, above all, in wake flows.
