ANSYS Fluent Helps Swimmers Capture The Gold in Beijing

August 15, 2008

The Speedo LZR Racer swimsuit is arguably the greatest technological achievement in the sport of swimming to date.  It's been a hot topic of discussion, and of controversy at the Olympic Games in Beijing.  According to Time Magazine, as of August 13th, 33 of the 36 swimmers to medal at the games were wearing a LZR.  World records are being shattered each time swimmers hit the pool.  ANSYS Fluent played a crucial role in the suit's design and development.

After testing numerous fabrics in both a wind tunnel and in an aquatic lab to find one with the lowest possible drag, scientists and engineers turned to ANSYS Fluent Computational Fluid Dynamics (CFD) technology to analyze their design.

The suit features laser bonded panels, eliminating seams – and a corset-like design that is most effective around the buttocks.  The suit streamlines the area, which reduces drag and allows for the swimmer to move through the water more easily.

ANSYS Fluent was used to analyze the panels of the suit during the first 15 meters of a race as a swimmer pushes off the platform and glides through the water prior to taking the first stroke, or after turn when beginning a lap.  CFD was used to analyze areas that result in both skin-drag and form-drag as a swimmer moves through the water and make key adjustments to the suit’s design.
