Experimental and numerical aerodynamics investigation of car
Sagar Bhamre,  Mayur Makwana
This project work is carried out for the aerodynamic analysis of a conceptual car. There are two methods to analyze the aerodynamic features of vehicles and importantly the turbulence: the wind tunnel and computational fluid dynamics (CFD). Modeling of the car is done in CATIA V5 R19 software. Most of the concentration is given to the exterior design of the car, while the interior is not modeled. Further, using the software ANSYS Fluent, simulation of the airflow around the sides of the vehicle is made in purpose of making changes in the outer body of the vehicle to improve design in terms of reducing air resistance and improving aerodynamics. Most of the concentration is given by changing the value of angle between the hood and front windshield of the car, and analyzing the back of the car with and without rear spoiler. Continuing with the obtained simulation and leading with the modification of initial model, an existing model is redesigned. Further, simulation is done on the modified model. The results obtained by simulation in software are compared and analyzed. According to my assumption, redesigned model will have better aerodynamic properties.
Keywords- Automobile, Computational fluid dynamics, Vehicle.
