Abstract
A considerable degree of driving discomfort can be experienced when driving a vehicle in the wake of others. This is especially true in either wet or dusty conditions when both forward and rearward vision becomes obscured. This report investigates the wake properties of a typical saloon car from wind tunnel tests. Longitudinal and transverse velocity distributions derived from pressure measurements are shown for various downstream positions in the wake and the decay of turbulence intensity is obtained from hot wire anemometer results. A yawed flow is shown to have a strong influence on the wake.
