Kurzfassung
An experimental and numerical study was performed with a 1/15th scaled model of a typical European tractor-trailer configuration. The objective was to develop a new and practicable passive method which reduces the aerodynamic pressure drag by controlling the unsteady velocity field behind the trailer. The experiments included the measurement of the pressure distribution on the trailer base, the velocity wake based on particle image velocimetry and the resulting aerodynamic loads. A trailer underbody equipped with a full fairing and a rear diffuser with side plates is shown to reduce the aerodynamic drag coefficient by 2.4 %. The direct influence on the trailer wake and the resultant base pressure of the trailer is presented. The results of the also conducted Computational Fluid Dynamics (CFD) predictions confirm the effect of the drag reducing add-on devices on the velocity and pressure field in accordance to the experimental data.
