The influence of buoyancy upon near wake pollutant dispersal
… and canonic representation of a wake, and an Ahmed body, which acts as a simplified representation of a road passenger vehicle. There are six fundamental parameters which can be used to characterise the influence of buoyancy upon pollutant dispersal within a wake: the objects height and width …

Experimental and numerical investigation of the flow structures at the rear of three-dimensional bluff bodies
… issues for transportation systems. The standard Ahmed body (SAB) is a simplified representative three-dimensional (3D) bluff body that is known to produce the essential features of complex bluff bodies. This thesis studies the flow structures at the rear end of 3D bluff bodies to aid the …

Decreasing the Power Consumption of Hybrid Electric Vehicle Architectures
… of electrical systems. Aerodynamics of an Ahmed body is investigated with a drag reduction system proposed utilizing slot jets at the rear of the bluff body . Two separate systems show a decrease in drag of 16 and 25%. The paper also investigates the use of a phase change material for a …

Design optimization of aerodynamic drag at the rear of generic passenger cars using nurbs representation
… (NURBS) curve was used to represent the rear body of a generic passenger car model (the Ahmed Body) and the NURBS parameters were employed for geometry parameterization. These geometry parameters were systematically modified using design of experiments to obtain different geometries of the …
