CONCLUSSIONS


Quote:
1. Use of rear screen allows a reduction in aerodynamic drag of the vehicle model under consideration by up to ~6.5%. Efficiency of rear screens from point of view of drag reducing equally depends on configuration, dimensions and arrangement of screens as well as on model’s rear part configuration. The external mount of spare tire can be arranged to reduce drag.
Quote:
2. Rear fairing as part of flow separation area behind the vehicle can reduce aerodynamic drag of the vehicle with investigated configuration, by up to 26%. These results can be used at analysis of accuracy of calculation methods for defining aerodynamics of vehicles with separated areas. The results can also be useful for designers and design engineers in selection of vehicle external configuration.
Quote:
3. The other passive options also have potential to reduce drag. Front structural elements showed decrease in drag coefficient up to 2.24% and vortex generator showed a decrease up to 1.24%. There is scope to achieve additional improvement with the understanding of flow field and optimization of design.
