The research project in question uses the regulations as provide by the Society of Automotive Engineers (SAE) for their yearly racing event Formula SAE (FSAE) competition in Michigan (2015 FORMULA SAE RULES. (2014). SAE INTERNATIONAL).The objective is to develop a full aerodynamic package to be produced by the Indiana- university Purdue- University Indianapolis (IUPUI) Formula SAE team in the spring of 2015. The term ‘full aerodynamic package’ consists of the following. A nosecone to cover the front of the car designed to generate ‘downforce’ or reverse lift. An engine cover designed to provide healthy airflow to the rear aerodynamics. A floor or ‘diffuser’ designed to both manage the airflow under the vehicle and also to generate downforce. The diffuser is designed to work with multiple airfoils located at the rear and front of the vehicle.
As wind tunnel testing of these designs is not currently viable, the aerodynamic packages, once designed in Computer aided drawing (CAD), has been evaluated using Computational fluid dynamics (CFD) as a tool for quantifying Lift to Drag ratio, in addition to L/D, the analysis includes code generated to find out the center of pressure (COP) of the car . Multiple iterations of various design concepts have been done to improve/optimize these numbers before a final package is defined. Design tool used to here is Solidworks 2014 and the CFD tool used is STARCCM+ which is a product of CD ADAPCO.
