    Aerodynamic Devices to Reduce the Base- and Underbody Drag of Semitrailer Unit

  • Original language description

    An experimental study of aerodynamic optimization of semitrailer unit was performed. Attention has been paid to the reduction of base-drag by means of rear-end extension panels and tapered cavity. Semitrailer-underbody drag was optimized by means of sideskirts. Experiments were performed with a scaled 1 : 15 model in a wind-tunnel. Comparison of some results with measurements taken with the vehicle in natural size in 1 : 1 wind-tunnel is mentioned. PIV technique was employed for flow-field analysis downstream the semitrailer. Some preliminary results of CFD calculations of flow field downstream the optimized back are shown.
