Aerodynamics: why virtual testing is better than a wind tunnel


Virtual aero testing

The Jaguar F-Pace is the latest model to ditch wind tunnels in favour of computer simulations to reduce drag; it saves money

Manufacturers are moving away from wind tunnel testing and opting to use virtual simulation techniques instead in their quest to reduce aerodynamic drag.

By switching to computer simulations, engineers can model a car’s aerodynamics without even building one.

Virtual simulation techniques are not only quicker and less costly than using a wind tunnel but also yield better results.

One company, Exa, produces a software package called Powerflow that has now been adopted by many leading car makers, including Tesla, <a target="_blank" …read more
