Abstract

The primary objective of the study is to examine the drag coefficient and its effect on a bluff body. Drag plays a vital role in a bluff body than a streamlined body due to the creation of more wake region behind the body. So in order to remove the wake region, a skid is attached at different angles in the rear end of the bluff body. Then the 2D bluff body is analyzed using the K-epsilon turbulence model by Computational Fluid Dynamics in Fluent 6.3. The coefficient of drag (cd) for a unit rectangular bluff body is usually 0.643. The maximum reduction of drag is obtained by comparing Cd of the unit rectangular bluff body with the skid attached bluff body. A standard bluff body is examined with some modifications like skids located at different angles. A wind tunnel is used to test bluff body experimentally. The advantage of this work lies in fuel consumption variation of aerodynamic bluff bodies.
