Summary:

Due to energy and material considerations, vehicle manufacturers move in the direction of producing smaller and lighter vehicles. With further reductions in the weight of vehicles, aerodynamic forces emerge as a major factor in energy and stability calculations. The situation becomes more important when moving through driving tunnels. Because of the limited space of a driving tunnel, vehicles are usually forced to interfere severely. 1/25-scale models for domestic bus and passenger car are employed. Three-dimensional pressure measurements are recorded for analyzing the aerodynamic behavior and calculating the drag coefficient. Measurements are supported by numerical calculations and flow visualization. Results show that vehicle interference has a favorable effect on reducing drag. However, stability considerations should be noticed
