Research Experiences for Undergraduates in Automotive Technologies

Proposed Project:
Unsteady Aerodynamic Forces

The driving comfort of a car is determined by a complex interaction of aerodynamics, mechanics and human factors. This project deals with some of the aerodynamic aspects involved, especially those involving unsteady flows. In particular we concentrate on the unsteady aerodynamics forces exerted on the vehicle when overtaking or when driving behind other large vehicles. Such information is experimentally difficult to obtain, since the boundary conditions are instationary (moving ground, moving vehicles) and normally road or test track tests are employed. In cooperation with a large Bavarian manufacturer, such data on yaw and side-forces is available and the present project continues initial efforts to numerically simulate these flows. The REU student must have prior knowledge with CFD codes; however excellent supervision in the use of available codes will also be provided. The task will be to compute a very specific configuration and to draw comparisons with available experimental data.
