The introductory of dimple to the Ahmed body top surface as a drag reduction device

This review concerns drag decrease endeavors by including a drag diminishment device to lessen fuel usage of the vehicle. A streamlined feature impact is seen with an introductory of dimple as a drag decrease device on different estimated position of Ahmed Body top surface. This review cantering diminishes drag by controlling boundary layer separation by changing the surface structure with adjustment of golf ball dimple idea by utilizing Computational Fluid Dynamics (CFD) technique. The configuration at which the dimple at 208.8 mm on the upper body area of model shows prominent result as it contributes around 7.22% of drag diminishment.
