Abstract

Drag reduction is one of the most significant issues within the automotive industry. Pressure drag contribute more than 80% of the total drag and it is highly dependent on vehicle geometry due to boundary layer separation and formation of wake region behind the vehicle. Drag caused by pressure different at the rear and front of the vehicle is a major issue for all car segments especially bluff body cars segments because it contribute largest fuel consumption. Air suction or blown at the rear of bluff body can alter the flow pattern of the air hence, shrink the wake region which resulting in increase of rear pressure and reduce the pressure different between front and rear of the body. The objective of this study are to design a concept of drag reduction system that can change the pressure distribution and reduce drag coefficient (CD) of bluff body which is Ahmed body. The design and testing of the airflow correction device will be aided by Computer-aided Design (CAD) and computational fluid dynamic (CFD). The concept of the rear air flow correction device hopefully will alter the flow pattern which change the pressure distribution and reduce drag coefficient (CD). Hence, with full of positive expectation, hopefully this method of reducing drag by using rear suction or blown air flow correction device will be broadly used for bluff body car segments for entire world and the trend change toward further study of this concept.
