Abstract


Automotive aerodynamics is the study of the aerodynamics of road vehicles. Its main goals are reducing drag and wind noise, minimizing noise emission, and preventing undesired lift forces and other causes of aerodynamic instability at high speeds. Air is also considered a fluid in this case. For some classes of racing vehicles, it may also be important to produce down force to improve traction and thus cornering abilities. With an improvement in computer technology, manufacturers are looking toward computational fluid dynamics instead of wind tunnel testing to reduce the testing time and cost. The result of the simulations will be analyzing that different devices posed several different functionalities. The three-dimensional car model is developed in SOLIDWORKS. Computational Fluid Dynamics (CFD) is performed to understand the resistive force of the air on vehicle. CFD is carried out in ANSYS Fluent module to calculate Drag Coefficient (CD), Lift Coefficient (CL), Drag Force and Lift Force. Through comparison and analysis of different aerodynamic devices, the optimized car is designed to improve the aerodynamic characteristics.
