Aletheon Technologies (Pratt & Miller) - Case Study
It’s not just how fast a racecar goes that makes a design a winner, it’s also how fast it goes around the curves. In large part, speed in the curves is a function of how much “down force” is created by air flowing over the car’s surfaces.
Thus, much of the computational fluid dynamics (CFD) analysis of race cars has to do with making sure the airflow pushes down on the car as it does with how smoothly the car slips through the air. The major benefit of CFD in auto racing: Cutting down the high costs of building prototype cars and physically testing in them in wind tunnels and on race tracks.
