“…A car design can only be acceptable if its form drag and aerodynamic noise are both reduced at the same time. Many researchers have made use of CFD techniques [1][2][3][4] and aero-acoustics analysis [5][6][7] topics on acoustics have been studied throughout the years. For example, acoustic holography was adopted to identify the noise sources of a vehicle underbody [8].…”

a b s t r a c tThis study proposes an effective numerical model based on the Computational Fluid Dynamics (CFD) approach to obtain the flow structure around a passenger car with wing type rear spoiler. The topology of the test vehicle and grid system is constructed by a commercial package, ICEM/CFD. FLUENT is the CFD solver employed in this study. After numerical iterations are completed, the aerodynamic data and detailed complicated flow structure are visualized using commercial packages, Field View and Tecplot. The wind effect on the aerodynamic behavior of a passenger car with and without a rear spoiler and endplate is numerically investigated in the present study. It is found that the installation of a spoiler with an appropriate angle of attack can reduce the aerodynamic lift coefficient. Furthermore, the installation of an endplate can reduce the noise behind the car. It is clear that the vertical stability of a passenger car and its noise elimination can be improved. Finally, the aerodynamics and aero-acoustics of the most suitable design of spoiler is introduced and analyzed.

“…Consequently, it becomes quite evident that by inserting more knowledge into the conceptual design phase, relatively greater cost and performance benefits can be achieved out of the aerohydrodynamic design data. The arguments in support of the earlier approach to the later design practice are well acknowledged in the literature [12], [17] and [18].…”

A concept of knowledge based aerodynamic design data categorized as an aerodynamic database archiving system is presented, maintaining such a state of the art data and documentation resource on a national scale is of vital importance from the viewpoint of data availability/ interoperability, ensured reliability, upholding data standards and its safe handling and distribution. Efforts made locally for maintaining a repository of aero-hydrodynamic data, CFD database for validation and verification aspects along with ground tests and field test data is now required to be upgraded into an aero-hydrodynamics data archiving system, to serve the local design community.

In the present study aerodynamic tests were performed by using Solidworks Flow Simulation software (CFD) in 2 different designs of conventional cars, implementing a spoiler in the back of the car to reduce the drag and lift coefficients that occur through the movement of the air regardless of the design in the back of the car and improve aerodynamics. Analyzing the results it is obtained that the aerodynamics of the car is improved when a spoiler is placed to reduce the drag and lift forces.
