Bending a Soccer Ball with CFD


Recent results in computational fluid dynamics from the University of Sheffield’s Sports Engineering Research Group and Fluent Europe indicate that the shape and surface of a soccer ball, as well as its initial orientation, play a fundamental role in the ball’s trajectory through the air. In particular, the CFD researchers have increased understanding of the “knuckleball” effect, a technique sometimes used to confuse an opposing goalkeeper. The research group focused on shots resulting from “free kicks,” in which the ball is placed on the ground, as after a foul. Full Story
This work was performed on Sun systems on the SRIF2 HPTC Cluster Grid, which is funded as part of a successful bid to the Government’s Science Research Investment Fund (SRIF2):
* 256 x 2.4 Ghz Opteron CPUs using Sun Fire V40z servers
* 75% Nortel Gigabit switched architecture
* 25% Myrinet interconnect for high bandwidth low latency transmissions
* 10 TB of Serial ATA Sun 3511 Storage Arrays

About Rich
FlexRex began his life as a cartoon character I created a Sun Microsystems. As the world's first "fictional blogger," he appeared in numerous parody films that made fun of the whole work-from-home thing. Somewhere along the line, the Sun IT department adopted FlexRex as their spokesman in a half-dozen security awareness films for employees. So when I left Sun recently, I started FlexRex Communications, a Marketing company in Portland, Oregon.
