Formula SAE-Full Car, Front, & Rear Wing CFD Dynamic Analysis.

The front wing and a rear wing was successfully designed, analyzed, manufactured and validated for college's Formula SAE car.

Using CAD software an initial model of the wing was developed. This initial design was based on successfully validated airfoil data from the airfoil simulation tool XFLR. This tool helps in determining the values of Cd, Cl for different types of airfoil. It also helps in determining the optimum angle of attack for various range of velocities.

Using CFD results it was possible to increase the mechanical grip on tires significantly.
Various parameters such as negative lift, drag force, pressure contours, velocity distribution, to were studied extensively to further improvise the package. The results achieved during manufacturing were excellent and the finish of modified airfoils and endplates was also fine.

Using various experimentation, the values such as downforce, drag force, coefficient of lift, etc. were successfully validated. For dynamic values high velocity air was made to allow over the surface of the wings and the changes in the readings of weighing machine were noted. To validate the flow, colorful threads were taped on various positions on the wing. The direction in which this threads flattered were captured as images and compared with the streamlines from CFD results. Experimentation results validated the CFD results excellently.

A huge amount of mechanical grip can be generated on the tire of the car. This will increase the tractive force and cornering speed of the car and eventually improve its performance on the track
