"Aerodynamic optimization is critical to a successful world record attempt."

At the World Human Powered Speed Challenge, students from around the world compete to design and power a bicycle using only energy generated by the rider’s body. At 80 mph, 70 percent of the retarding forces acting upon a high-speed bike result from drag upon the carbon-fiber monocoque shell, so aerodynamic optimization is critical to a successful world record attempt. Employing the easy-to-use ANSYS CFD software featuring the transition SST turbulence model, the University of Liverpool Velocipede Team optimized the aerodynamics of the shell upfront in the design process so that it could be manufactured in time for testing and competition.

The University of Liverpool Velocipede (ULV) Team was sponsored by Rathbone Investment Management and supported by Friends of the University of Liverpool.
