A Review of Measurement of Ambient Turbulence with Respect to Ground Vehicles

This review paper presents an analytical framework for measuring the turbulent environment of ground vehicles, motor cars in particular, both on the road and in wind tunnels. It is suggested that this framework can be used to start to measure and assess the level of modeling required of the natural wind environment of motor cars and the turbulent environment needed in wind tunnels. This approach should also be adopted for vehicle aerodynamics and associated acoustics problems and computational fluid dynamics simulation. This approach should also supply the framework by which the importance of turbulence for vehicle aerodynamics can be rigorously assessed.
