Abstract
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 (C
FD) 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 imp
ortant 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.
