Aerodynamic Simulation Reveals Best Position in a Peloton of Cyclists

HPC Wire, July 2018

The position of a cyclist in a race could affect its outcome. But what is the best position? Researchers at Eindhoven University of Technology and KU Leuven, led by Professor Bert Blocken, ran a 3-billion-cell ANSYS Fluent simulation on a Cray computer to find out. By determining the flow pattern between each cyclist in the peloton, the team found that the riders at the core of the peloton experience much less drag than was previously expected. This was the largest CFD model ever performed for sports.
