AB  - In this study, the effects of grilles in a vehicle on the aerodynamicdrag coefficient and energy loss have been investigated. For this purpose,grilles have been placed horizontally to the front of the vehicle. Firstly, theaerodynamic drag coefficient and aerodynamic energy loss of the vehicle modelwithout grilles have been determined numerically. Then, the aerodynamic losscoefficient and the aerodynamic energy loss of the vehicle model with grilleshave been determined. Thus, the effect of the grilles placed in the front ofvehicle on aerodynamic resistance and energy loss is compared to the vehiclemodel without grilles. For all estimates, the vehicle models have been modeledin SolidWorks software. ANSYS-Fluent software has been used for numerical analysisfor the modeled vehicles. It has been determined that the grilles placed in thefront of vehicle increased the aerodynamic drag coefficient of the vehicle andthus the aerodynamic energy loss of the vehicle increased. Thus, it has beenshown that it is possible to reduce a certain extent the additional aerodynamiclosses in the vehicle by approaching the grilles designs closer to the vehiclemodel without grilles.
