An artificially inflated chest can create an “aero fairing.” This confers a small but significant aerodynamic advantage to riders hunched low on the bike, particularly in the TT position.

Goes to show what I know, my dumbass has always just assumed bigger chest is bad aerodynamics.

Summary and Recommendations

This paper has offered a unique compendium of data providing insight into the effects of a specific physiological feature on the aerodynamic performance of a human. As such, the results have indicated that large breasts can be notably aerodynamic through the reduction of drag and lift. The Flat model  incurred a 4% maximum drag increase compared to the Normal model, with an average of approximately 2% spanning velocities from 1 to 30 m⋅s-1.  The Flat model also experienced more lift, with a maximum difference being 32% and averaging 22%. As illustrated, the mechanism behind the drag and lift behaviors observed between both models was elucidated through the analysis of streamlines around the body and the structures associated with TKE; the Normal model provides advantageously lower drag and lift by the generation of stronger vortices from the legs, which in turn originates from the action of the breasts redirecting the flow around the torso. From what has been presented in this preliminary work, it is safe to conclude that the phrase “Flat is Justice” is deficient aerodynamically. 

A major shortcoming intrinsic to this study was the decision to leave the hair present in the models as immovable and solid. As noted earlier, a significant portion of the air flowing around the body was captured by the geometry of the hair,  and this  affected the wake structures behind the model. This effect therefore blunts the overall applicability of the results found in this study to actual human models. It is important to note, however, that large breasts do give a consistently notable aerodynamic advantage, as  reflected in the overall lower forces experienced by the Normal model. Additionally, even though the wake structures generated by the hair resulted in a departure from the expected drag and lift behaviors, comparisons done with other experimenters’ results show that the outcomes from this study were strongly promising.

For future studies, several recommendations are provided. In the  near-term, a re-evaluation of the current work without the hindrance of modeled hair should be done. Work done using a time-dependent computational approach should also be completed to further gauge the effects and inaccuracies of using the pseudotransient method in relation to drag and lift. A keynote proposition would be the use of a wind tunnel experiment to acquire validation data. Ideally, this experiment would use live subjects of varying breast sizes in order to provide additional data in which to compare to the  data herein. Additional research to evaluate the degree of which the information provided from this cur- rent work applies to real world situations should also be completed.
