Computational Analysis of Frontal Area of a Front Grill Passenger Car

Abstract:

Designing the front grill with the focus on analyzing the flow from outside to the inside of a passenger car bonnet is very important in the automotive industry. This study was done to increase performance of the flow through the analysis on the effect of aerodynamic flow through the front grill by designing different cases of frontal areas of the front grill. Velocity at 34 m/s at steady condition were done to obtain the flow structure around a passenger car as well as the front grill of a passenger car. Analysis was taken inside the wind tunnel as the boundary condition. The grid generation was based on the tetrahedral unstructured meshes. Result obtain was compared with past experiment data. It was found that an appropriate design of frontal area of front grill can improved the stability of a car and the heat surrounding inside the car bonnet. Finally, the aerodynamics of the most suitable design of front grill was introduced and analyzed.
