To Build a Better Bobsled

Learn how supercomputers helped construct a faster bobsled for the 2010 U.S. Olympic Team

Pressure Drop

Here's where it all comes together for the design team. In this simulated image an Exa PowerFlow graphic is overlaid onto a photograph of a U.S. bobsled on a track to show the real-world effects of wind resistance during a run. The red areas again show high surface pressure--which is what engineers want to decrease--while the blue regions represent low pressure. The goal is always to reduce frontal high pressure to quicken the sled's path through the air, while also trying not to increase low pressure at the rear, which can slow the sled.
