ABSTRACT. This work summarizes the process of developing an aerodynamic package of a Formula Student Race Car with the help of computational fluid dynamics and validation of the same through experimental work. Investigation in this work is based on the effects of aerodynamic package on the vehicle’s behavior and performance with regard to the Formula Student competition rules. The aerodynamic package consist of front wing and rear wing of the vehicle that increases the normal load on the tyres and aids in increasing the cornering stiffness within an operating range, thus improving the cornering capabilities of the vehicle. The methods used during the development are evaluated and put into context by investigating the correlation between a constant velocity experiment of the wings and its simulated counterpart. In constant velocity test the car reaches up to a particular velocity which is 14 m/s in our case and continues to maintain that velocity over 250 m long stretch. The test is conducted several times with and without aerodynamic package, the readings are recorded with the help of linear potentiometers which are attached along with the damper mounts. The data obtained from the potentiometer is logged by the data logger. The constant velocity test data helps to validate the experimental data with the CFD. The work also details the stages involved in optimizing these components to achieve the desired results.
