This review surveys the problem of surface contamination of cars, which poses a growing engineering challenge to vehicle manufacturers, operators and users. Both the vision of drivers and the visibility of vehicles need to be maintained under a wide range of environmental conditions. This requires managing the flow of surface water on windscreens and side glazing. The rate of deposition of solid contaminants on glazing, lights, licence plates and external mirrors also needs to be minimised. Maintaining vehicle aesthetics and limiting the transfer of contaminants to the hands and clothes of users from soiled surfaces are also significant issues. Recently, keeping camera lenses clean has emerged as a key concern, as these systems transition from occasional manoeuvring aids to sensors for safety systems. The deposition of water and solid contaminants on to car surfaces is strongly influenced by unsteady vehicle aerodynamic effects. Airborne water droplets falling as rain or lifted as spray by tyres interact with wakes, vortices and shear flows and accumulate on vehicle surfaces as a consequence. The same aerodynamic effects also control the movement of surface water droplets, rivulets and films; hence, particular attention is paid to the management of surface water over the front side glass and the deposition of contaminants on the rear surfaces. The test methods used in the automotive industry are reviewed, as are the numerical simulation techniques.

Tire spray generated as automobile or truck tires roll over a wet roadway is a familiar hazard to all drivers. Past efforts to mitigate the effects of tire spray have focused on inventing and testing add-on devices to suppress, redirect, or contain spray. These devices have had only limited success in controlling spray. An alternate approach would be to examine tire spray at the source—the tire and wet roadway. This article describes a device designed to simulate tire spray in a laboratory setting, allowing a careful examination of spray in a controlled environment. The device limits the spray to that produced from water passing through a tire groove and then carried away from the roadway by the rotating tire. The spray pattern downstream of the tire patch is captured with high-speed video and stored on disk. The video images are then processed as desired by computer. A concept “time-to-drain” is introduced to characterize the angle at which spray leaves the tire. Time-to-drain is then used to compare the spray patterns of different tires.
