Summary:

Two domains of aerodynamic testing of vehicles are identified; one representing typical driving conditions, where the average atmospheric wind is less than about 10 m/s; the other representing driving under extreme wind conditions for safety considerations. The first domain influences fuel consumption and other parameters related to driving comfort (e.g. aerodynamic noise, transient forces and transient moments experienced during general driving), whereas the second needs to be assessed for stability considerations.The purpose of this paper is to document turbulence commonly encountered by vehicles moving at highway speeds under typical driving conditions. In order to document this, data obtained from hot-wire anemometers fitted above a moving vehicle are presented. It was found that longitudinal and lateral turbulence intensities ranged between 2.5% to 5% and 2.0% to 10% respectively. Spectral results showed the peak energy was centred at about 1 Hz although it varied between about 0.25 Hz to 2.5 Hz. Wind-tunnel modelling is discussed
