This paper presents the first experimental and computational investigation into the aerodynamics of emergency response vehicles and focuses on reducing the additional drag that results from the customary practice of adding light-bars onto the vehicles' roofs. A series of wind tunnel experiments demonstrate the significant increase in drag that results from the light bars and show these can be minimized by reducing the flow separation caused by them. Simple potential improvements in the aerodynamic design of the light bars are investigated by combining Computational Fluid Dynamics (CFD) with Design of Experiments and metamodelling methods. An aerofoil-based roof design concept is shown to reduce the overall aerodynamic drag by up to 20% and an analysis of its effect on overall fuel consumption indicates that it offers a significant opportunity for improving the fuel economy and reducing emissions from emergency response vehicles. These benefits are now being realised by the UK's ambulance services.

“…Aerodynamic drag is the force opposite to the direction of motion that acts on a body moving through air. In the past two decades, CFD has been used widely in vehicle aerodynamic studies [5,6]. Many companies and universities are paying increasing attention to the development of automotive aerodynamics [7,8], where a drag reduction by 2-6% would result in a significant reduction in fuel consumption [9].…”

Computational fluid dynamic (CFD) is a flow modelling technique which utilizes iterative methods to solve continuity and momentum equations along with any appropriate auxiliary equations depending on the application. This paper studied the effect of front and rear windscreen angles of a car on the drag force for the case of the Citroen C5 2007. Numerical results were obtained based on the finite volume method (FVM). The aerodynamic behavior of the car was studied with different front and rear windscreen angles. The initial results helped to estimate an optimal shape for the car based on the least drag coefficient. Consequently, an optimal car shape is proposed by improving the car's aerodynamic design including the surface roughness and windscreen angles. This has potentially reduced the drag coefficient by 8.88 % compared to the initial design. This would offer a significant opportunity for reducing the fuel consumption.

“…The focus of recent studies has been on the drag reduction of Heavy Goods Vehicles, see e.g. [1,4,5,6,7]. Currently there have been relatively few studies on the aerodynamic improvement of light trucks and cars [8,9], while a small number still have reported reduced aerodynamic drag using automated design optimization techniques [2,8,10].…”

This paper investigates the optimization of the aerodynamic design of a police car, BMW 5-series which is popular police force across the UK. A Bezier curve fitting approach is proposed as a tool to improve the existing design of the warning light cluster in order to reduce drag. A formal optimization technique based on Computational Fluid Dynamics (CFD) and moving least squares (MLS) is used to determine the control points for the approximated curve to cover the light-bar and streamline the shape of the roof. The results clearly show that improving the aerodynamic design of the roofs will offer an important opportunity for reducing the fuel consumption and emissions for police vehicles. The optimized police car has 30% less drag than the non-optimized counter-part.
