A Study on the Influence of the Flow Field around the Front and Rear Wings on the Resistance of F1 Racing

Abstract

In the racing field of F1 cars, the size of wind resistance and the flow field distribution of the environment around the car at high speed play a key role in the driving speed and turning speed of the car. The amount of wind resistance is controlled by a system called DRS, which controls both the nose and the rear wing of an F1 car. In this paper, the influence of the design of the front wing and rear wing on the air resistance of the car in driving is introduced in detail. The fluid characteristics around the F1 car are analyzed by analyzing the wind resistance and wind force in various places during driving. In addition, this paper will analyze the formation of the tail-vortex of the racing car, control the strength of the tail-vortex system and reduce its turbulence degree, and at the same time reduce the turbulent energy consumption of the air flow to achieve the purpose of drag reduction. The research shows that the formation of tail-vortices is the main reason for the drag of automobile driving. We want to reduce the drag of tail-wing and weaken the formation of these vortices.
