Rough CFD Simulation
by: BTR Forum Member: zebragonzo
This model is intended to show the flow of air around a rider and to give armchair aerodynamicists a chance to better understand how air flows.
Because of the complexity of the model and the limited time available to run it, the mesh has had to be simplified such that the accuracy isn't spot on. Additionally, the legs and wheels are not rotating. Finally, there are some areas that did not mesh quite correctly (front of the chainring, some of the rear wheel, top of the down tube). Despite these errors the simulation reports a drag of 2480g for both the rider and bike which is as would be expected for a cyclist in this position thus indicating that the error isn't sufficiently high that the model does not resemble real life.
