A computational fluid dynamics methodology is used to study the salient flow features around the breasts of a human figure and to describe the aerodynamic differences imparted by their geometric presence.
2 models are proposed for examination: a 3-dimensional reference based on a character design with a largely buxom figure and a modification of this design where the breast size is reduced largely. The 2 models are tested at speeds ranging 1–30 m⋅s−1 using Reynolds-averaged Navier Stokes (RANS). Drag, lift, and skin friction forces, along with turbulence kinetic energy (TKE), are investigated and compared between the different models.
The present results are expected to provide useful information on the validity of the statement, “Flat is Justice” in terms of an aerodynamic standpoint. In addition to this, the results can offer worthwhile data investigating the anthropometrical presence of large breasts on sport aerodynamics.
