This report presents the results of a CFD study to develop a bodywork package to improve the aerodynamic performance of the Brigham Young University (BYU) Electric Streamliner. A comparison of the pressure distribution and the flow around the baseline and final ‘recommended’ configuration is also presented.
The effect of the CFD developed body geometry to the vehicle has been to increase downforce by almost 300lbf when it is at 200mph, while reducing drag by 8.5lbf. The final lift to drag ratio is -1.56 as compared to the .67 baseline.
