IVA’s Division for Basic and Interdisciplinary Engineering Sciences welcomes you to a seminar that will give some insights into the future development of both high-performance cars as well as commercial vehicles.
Aerodynamics has advanced over more than a hundred years to allow the development of todays commercial and military aircraft, but has also become important for vehicles in the heavy-duty sector as well as for passenger cars. Here the focus is on lowering drag, thereby leading to better fuel economy and to less CO2 emissions. On the other hand, high-performance vehicles (sport and race cars) instead have to be designed for sufficiently strong negative lift in order to increase their cornering and braking capabilities.
Aerodynamics of ground vehicles is clearly more complicated than that for commercial aircraft. For example, interaction with the ground, complex geometries, spinning wheels, cooling of the engine and brakes, the necessity to be able to drive in rain or snow, all have to be accounted for in the aerodynamic design of a vehicle.
Today the tools that are used for design of both aircraft and vehicles are steadily improving, both due to new experimental diagnostics but also due to increased computer power that allows the designer to model the Navier-Stokes equations and thereby solve the flow field numerically.
