Research of the flow structure and experiment data on full and small scale cyclist model

Abstract

As the progressing of the bicycle race reducing aerodynamic drag has become the key to improving the performance of the competition Therefore to have an effective improvement in the future a further understanding of the surrounding flow field conditions and experimental problems can be significant In this study we start with two wind tunnel experiment data on full-scale cyclist models analysing the flow characteristics and aerodynamic performance with a cyclist model at the dropped position The computational fluid dynamics is used to collect more detailed flow field information such as surface flow separation limiting streamline vortex structure development etc Also by using the same geometry 1/5 scale model in a small wind tunnel evaluated by wake structure drag and visualization experiments with the use of water channel carried out to study the flow field similarity between the scale model and the full-scale model
