Aerodynamics of Heavy Vehicles Driving Past a Wall
Printer-friendly versionPDF version

The aerodynamic pressure eld generated by passing vehicles was investigated providing measurements and Computational Fluid Dynamics (CFD) simulations. Furthermore,the focus is lying on heavy vehicle shapes because of their larger frontal area compared to cars. However, to understand the mechanisms for the pressure eld generation also a sedan model and a generic heavy vehicle shape was introduced. Interesting flow features are found with a clear allocation to the underbody blockage of all vehicle shapes. In addition, the influence of rotating wheels on the pressure distribution on the wall was studied.
