Modelling the aerodynamics of a time trial bicycle
 

Hi,
I am doing a group project looking in to the aerodynamics of a bicycle and how they may be improved. I am researching performing CFD around a body in ansys. I have performed CFD analysis for the flow in a pipe and have been following the tutorial by scopy on youtube to help me understand how to perform this analysis. However, how would i go about making items like the wheels rotate at a steady speed to help with the analysis?

I don't know what is your geometry. Are the wheels totally faired? If so, I sugest you to use the MRF formulation. If not, and you don't have enough resources, use MRF too. If you have enough resourses and time, the better option is to use sliding mesh formulation. Take a look at the tutorials and FLUENT user's guide about these topics. I hope this helps you. Regards. Gonzalo
