Comparing Aerodynamic Design stability of Passenger Cars Manufactured for Indian Conditions
Keywords:
Passenger vehicles, Aerodynamic drag, CFD analysisAbstract
The primary objective of this study is to compare the aerodynamic impact and stability of passenger vehicle which are used in India. To measure and compare the aerodynamic drag of two car models widely used on Indian roads in north India, computational fluid dynamics simulation using FLUENT software was used to visualize airflow around the car geometry. CFD analysis achieved was used to analyse the critical places in geometry which result in unfavourable aerodynamics of moving car. The aerodynamic drags on the baseline models at different sides of the cars (i.e., front faring, side skirting and gap filling) were measured for both the vehicle operating at same speeds and yaw angles, and with different combinations. The results show that the different car geometry has notable impact on aerodynamic drag and stability.
