Formula One (also known as F1) is the highest class of single-seater open-wheel and open-cockpit professional motor racing contest. Formula One racing is governed and sanctioned by a world body called the FIA − Fédération Internationale de l'Automobile or the International Automobile Federation. The name ‘Formula’ comes from the set of rules that the participating cars and drivers must follow. The car is naturally the central component in F1. There is not much room to differentiate in the design of the engine and wheels of F1 cars, there are only 4 engine manufacturers and Pirelli is the sole supplier for all team’s tyres. As there is not much scope for innovation in these aspects of an F1 car, most innovation is left to the aerodynamic design of the F1 car. The aerodynamics team considers many different principles when designing the car. In this paper, we will be first examining these aerodynamic principles and then discussing how they are applied to F1 cars. A survey has also .
See Full PDF See Full PDFThe most important consideration in " Formula One " (F1) car design is Aerodynamics. " Aerodynamics " is the way air moves around things [1]. It is the difference between championship challenging car and a tail car [2]. Simply, F1 car aerodynamics design has to consider primary concerns: minimizing drag resulting from air resistance; and increasing downforce to push the car tires onto the track and stabilize the car during cornering. This paper discusses the aerodynamics and the resulting forces on F1 car body using CFD. Solidworks 2015 software [3] was employed to create the 3D model used in the simulation. The model was available on GrabCAD [4]. Also, ANSYS Fluent, v.17.1 [5] was used to simulate and analyze the aerodynamics of the car when it is running in a straight line, and cornering. Drag and lift coefficients, velocity streamlines and pressure contours were calculated and presented as results of this simulation.

The design for aerodynamics of front-body of a Formula-One car plays an important role on the car's performance. The endplates are attached at the end of front wing to reduce turbulence. Endplate deflects flow away from wheel to reduce drag. Proper orientation of airfoil gives maximum down-force with least drag-force acting on the front wing. For orientation of the airfoil, an optimum angle of attack for the wing is determined, which corresponds to maximum lift-drag ratio. The aerodynamic performance of Formula-One car is determined by measuring the drag-force and down-force acting on the car. Various geometric models of the car are created in the CAD package CATIA V5. The CFD analysis is done by using ANSYS FLUENT. It shows the flow pattern over the car. The behaviour of the flow is greatly influenced by the front wheels which were simulated with the front wing and therefore the design has to take into account the environment of the front wing. The endplates demonstrate their utilities as deflectors that are able to deflect the flow outward to the wheels. They also show that the additional down-force can be created by attaching a plate to the endplate at the end of wing.

This paper explores the role of the computational fluid dynamics (CFD) modeling technique in the aerodynamic design and propulsion system of the formula 1 car. It provides a study of Reynolds number influences on the state of the boundary layer, unstable and steady flow, time-dependent wake structure, interacting shear layer and separate flows through literature review. As pointed out in is paper, the aerodynamics analysis is conducted to decrease the drag force. Using the computational fluid dynamics (CFD) tools, the analysis was carried out. The major objective of this review article will be to increase the car stability and reduce drag. The efficiency of the track would also increase the air resistance of the vehicle. The ideas of dimensional analysis and uniformity of flows are used to demonstrate that commercial ground cars' aerodynamics are only dependent on the transitional and trans-critical flow regimes.
