A WIND TUNNEL INVESTIGATION OF MUD DEPOSITS ON THE BODY OF A BUS

Mud and dust deposits on bus bodies pose a danger to traffic and spoil the appearance of the vehicle. Of the three phases of the soiling process -dispersal, transport and separation of particles -it is mainly the transport phase that can be influenced by controlling the aerodynamic flow field in such a way that the mud or dust laden air avoids the protected areas of the body. Wind tunnel investigations have been carried out to determine the influence of several geometrical parameters on the surface deposits. Two methods have been developed and have proved to yield quantitative results. Simulation of the road by means of a moving belt has had a significant effect on surface deposits. The rear wall deposits depend mainly on the structure of the wake and the characteristics of the underbody flow. Both can be affected beneficially by the shape of the bus body. (Author/TRRL)
