() Investigation of Influence of Adjustments in Cyclist Arm Position on Aerodynamic Drag Using Computational Fluid Dynamics. Proceedings, 49 (1).en_USctIn professional cycling, even small adjustments in position could mean that valuable seconds are gained over the course of a time-trial race.

This study investigates the influence of arm position on the aerodynamic drag of a cyclist.

Principles of turbomachinery in air-breathing engines

Based on a 3D scanned model of a professional cyclist, 64 alternate positions are generated. The parameters that are investigated are the distance between elbows, elbow extension, and distance between hands. Computational fluid dynamics (CFD) simulations of all positions are performed, and a regression model is built from the results.

The results indicate that the optimal posture is achieved for a minimum in
