A Large-scale Aerodynamics Study on Bicycle Racing
Aerodynamics studies for bicycle racings have been carried out by using a CFD simulation based on LES model. For running of alone cyclist and 2─4 cyclists groups, the computational drags are in good agreement with the wind-tunnel experiments. Different shapes of group running and competing two teams are studied. A large-scale computation for a group of 72 cyclists has been performed by using 2.23 billion meshes on a GPU supercomputer.
